The family members supported Mr. Robert in the beginning that he was on the right path. They thought that his bank job would not disturb. He would continue to work there.

परिवार के सदस्यों ने प्रारम्भ में श्री रॉबर्ट का साथ इसलिए दिया क्योंकि वह सही रास्ते पर था। उन्होंने सोचा कि उनकी बैंक की नौकरी बाधित नहीं होगी। वह वहाँ पर निरन्तर काम करता रहेगा।

Robert was working as an assistant of John Gresham. There was a crash in the bank. Robert was the only one witness. John Gresham offered him a large amount only to keep quiet or to say “I do not remember.” Robert refused to take the amount. This whole incident was told by John Gresham to Mr. Marshall. He was very impressed with his honesty. Robert was Jobless. At that time Mr. Marshall visited his house to offer him a job. He had only this reason to visit his house.

रॉबर्ट जॉन ग्रेशम के एक सहायक के रूप में कार्य कर रहा था। बैंक में अचानक एक घोटाला हो गया था। रॉबर्ट एकमात्र गवाह था। जॉन ग्रेशम ने उसे एक बहुत बड़ी राशि की पेशकश की केवल चुप रहने या यह कहने कि “मुझे याद नहीं है।” रॉबर्ट ने पैसा लेने से मना कर दिया था। यह सारी घटना जॉन ग्रेशम ने मार्शल को बताई थी। वह उसकी ईमानदारी से बहुत प्रभावित हुआ था। रॉबर्ट नौकरी विहीन था। उस समय श्री मार्शल उसके घर उसे नौकरी देने आए थे। उसके घर पर आने का यही एक कारण था।

The Hour of Truth title is fit to its content matter. Truth and honesty is widely discussed in this play. It is well said that ‘Truth prevails in the end.” It is also said that the truth has to pass so many tests in life. Truth has to suffer but it wins in the end. The title of the play tells that truth is rewarded adequately. The Hero of this play who was jobless in the end was rewarded by dint of his honesty only. The person, who is honest, need not prove his honesty. People say when the hour comes, God rewards him.

सत्य का समय शीर्षक इसकी विषय-वस्तु के अनुकूल है। इस एकांकी में सत्य और ईमानदारी पर विस्तार से चर्चा की गई है। यह सही कहा गया है कि “अन्त में सत्य की जीत होती है।” यह भी कहा गया है कि सत्य को कई परीक्षाएँ अपने जीवन में पास करनी पड़ती हैं। सत्य परेशान होता है परन्तु अन्त में जीतता है। एकांकी का शीर्षक यह बताता है कि सत्य को पर्याप्त रूप में पुरस्कृत किया जाता है। इस एकांकी का नायक जोकि नौकरीविहीन हो जाता है उसे अन्त में केवल ईमानदारी के लिए पुरस्कृत किया जाता है। व्यक्ति जो ईमानदार है उसे अपनी ईमानदारी को साबित करने की आवश्यकता नहीं है। लोग बातें करते हैं जब समय आता है भगवान उसे पुरस्कृत करते हैं।

Mr. Robert was working as an assistant in the bank. He was working under Mr. Gresham. He was very old. He had a son and a daughter. He had a wife who looked after home. Mr. Robert was an honest man. He was very sincere and loyal to his work and duty. Whatever he did he always had notes of the work. We came to know that he was very close to his boss Mr. Gresham. He was his faithful assistant. Mr. Robert came to know about a wreck in the bank.

He knew on the last day. Robert knew everything. Gresham was arrested by police. He sent for his faithful man to perjure in the court. He was offered a bribe of hundred thousand dollars. Robert did not like it.’ He was very bold and firm in his decision. His family members could not disturb his decision. He scolded them all. He was rewarded for his honesty at the end when the president of Third National came to his home and offered him a job.

रॉबर्ट बैंक में एक सहायक के रूप में काम कर रहा था। वह श्री ग्रेशम के अधीन काम करता था। वह बहुत बूढ़ा था। उसके एक बेटा और बेटी थे। उसकी पत्नी घर की देखभाल करती थी। रॉबर्ट एक ईमानदार आदमी था। वह अपने काम और नौकरी के प्रति सच्चा और ईमानदार था। जो कुछ वह करता था वह अपने काम की टिप्पणी लिखता था। हमें पता चलता है कि वह अपने अधिकारी ग्रेशम का नजदीकी था। वह विश्वासपात्र सहायक था।

रॉबर्ट को बैंक के दिवालियापन का पता चला। उसे अन्तिम दिन यह पता चला। रॉबर्ट सब कुछ जानता था। ग्रेशम को पुलिस ने गिरफ्तार कर लिया। उसने अपने विश्वासपात्र व्यक्ति को कोर्ट में झूठी गवाही के लिए बुलाया। उसे एक सौ हजार डॉलर की घूस की पेशकश की गई थी। रॉबर्ट ने उसे नहीं लिया था। वह अपने निर्णय में दृढ़ और मजबूत था। उसके परिवार के सदस्य उसके निर्णय को बाधित नहीं कर सके। उसे अन्त में उसकी ईमानदारी के लिए पुरस्कृत थर्ड नेशनल के अध्यक्ष द्वारा उसके घर आकर नौकरी देकर किया गया था।

Mr. Robert had been very sincere, honest and loyal to his job. When his family members came to know that he was offered a bribe of hundred thousand dollars, they all pressurised him. They told him that it was a very big amount. He could start his own business with that money. They all said that he had to do nothing

Mr. Robert was very sad to know all this. He had come to know about his family members. He was very surprised over it. He told them that to perjure in court is very difficult. His throat will be choked. He warned them all that nobody had raised finger on his honesty. He had a social reputation. He did not want to die with a stain. He would go to his grave clean.

श्री रॉबर्ट बहुत गम्भीर, ईमानदार और नौकरी के प्रति वफादार रहे थे। जब उनके परिवार के सदस्यों को पता चला कि उसे एक सौ हजार डॉलर की घूस की पेशकश की गई थी, उन सबने उस पर दबाव डाला। उन्होंने उससे कहा कि यह एक बहुत बड़ी राशि थी। वह अपना स्वयं का व्यापार शुरू कर सकते थे। उन्होंने सभी ने कहा कि उसे कुछ नहीं करना था। रॉबर्ट को यह सब जानकर बहुत दु:ख हुआ था। उसे अपने परिवार के सदस्यों के बारे में पता चला। वह इस पर बड़ा आश्चर्यचकित हुआ। उसने कहा कि कोर्ट में झूठी गवाही देना कठिन है। उसका गला रुक जाएगा। उसने उन सबको चेतावनी दी कि किसी ने उस पर अंगुली नहीं उठाई थी। उसकी सामाजिक प्रतिष्ठा थी। वह कलंक के साथ नहीं मरना चाहता था। वह कब्र में साफ जाएगा।

His wife was accompanied by his son and daughter when they all were unitedly pressurising him to accept the bribe. Mr. Robert did not want to accept the bribe. He was told by them to start a business with the money. Robert told them that he was known for his qualities in the society. He was very honest. They at last told him to keep quiet in the court. Robert was not ready for all this. He lost his control then. He scolded his family with these words. These words were the symbol of his honesty. His anger towards all those who talk of honesty but they are also culprits, because they wish to disturb the system.

उसकी पत्नी अपने बेटे और बेटी के साथ मिल गई थी जब वे सब मिलकर उस पर दबाव बना रहे थे कि वह घूस स्वीकार कर ले। रॉबर्ट घूस लेना नहीं चाहता था। उसको कहा गया कि वह उस धन से कोई व्यापार शुरू कर सकता था। रॉबर्ट ने बताया कि वह अपने गुणों के लिए समाज में जाना जाता था। वह बहुत ईमानदार था। उन सबने उससे कोर्ट में चुप रहने के लिए कहा था। रॉबर्ट इन सबके लिए तैयार नहीं था। तब उसने अपना नियन्त्रण खो दिया। उसने अपने परिवार को इन शब्दों से फटकारा है। ये शब्द उसकी ईमानदारी के प्रतीक थे। उसका गुस्सा उन लोगों के प्रति था जो ईमानदारी की बातें करते हैं और वे वास्तविक अपराधी हैं क्योंकि वे प्रक्रिया को बाधित करना चाहते हैं।

(i) False

(iii) True

(iv) True

(i) 39 M 2

The given number = 39 M 2

Sum of its digits in odd places = 3 + M

Sum of its digits in even place = 9 + 2 = 11

Their Difference = 11 – (3 + M)

11 – (3 + M) = 0 

11 – 3 = M 

M = 8

(ii) 3 M 422

The given number = 3 M 422

Sum of its digits in odd places = 3 + 4 + 2 = 9

Sum of its digit in even places = M + 2

Difference of the two sums = 9 – (M + 2)

9 – (M + 2) = 0

9 – 2 = M

M = 7

(iii) 70975 M

The given number = 70975 M

Sum of its digits in odd places = 0 + 7 + M = 7 + M

Sum of its digit in even places = 5 + 9 + 7 = 21

Difference of the two sums = 21 – (7 + M)

=> 21 – (7 + M) = 0

=> 21 = 7 + M

=> M = 14

Since, M cannot be two digit number M = 14 – 11 = 3

(iv) 14 M 75

The given number = 14 M 75

Sum of its digit in odd places = 1 + M + 5 = M + 6

Sum of its digit in even places = 4 + 7 = 11

11 – (M + 16) = 0

11 = M + 6

11 – 6 = M

M = 5

i. Boron

ii. Aluminium

Boron is glossy and hard solid like metals but a poor conductor of electricity like nonmetals. Since it exhibits properties of both metals and nonmetals, boron is classified as a metalloid.

i. Metal: Tin, lead 

ii. Nonmetal: Carbon 

iii. Metalloid: Silicon, germanium

The basic assumption of obtaining Bowley’s measure of skewness is “In a skewed frequency distribution the extreme quartiles Q₁ and Q₃ are not equidistant from the median M (Q₂)”.

Given tan^-1 (1/x) 

\(=tan^{-1}(-\frac{1}{x})\) for x < 0

\(=tan^{-1}(\frac{1}{x})\)

= cot^-1 x 

= - (π – cot^-1 x) 

= - π + cot^-1 x

We know that the value of cosec^-1 (√3/2) is undefined as it is outside the range i.e. R-(-1,1).

We know that the value of cosec^-1 (√3/2) is undefined as it is outside the range i.e. R-(-1,1).

Let y = cosec^-1(√3/2)

We know that,

Domain of y = cosec^–1 x is (– ∞, 1] U [1, ∞]

But √3/2 < 1

Therefore, it can not be a value of y.

Hence, Set of values of cosec^–1(√3/2) is a null set.

(c) was a movement against alcoholism started by the women.

1 – B ; 2 – C ; 3 – D; 4 – A

In the 1970s and 80s, there are many groups of people that were not satisfied with the working of the existing political parties. This caused the formation of non-political groupings. In many spheres they were able to bring about changes. Even then economic inequality and poverty remained on a large scale. The benefits of the economic gains did not reach all levels of the population. There was a big gap between the industrial and rural sectors. Many felt this was injustice.

Many political parties lost their faith in the democratic system. Therefore they were forced to adopt new methods. Students, subalterns and Adivas is joined together and worked for the poor people, fighting against social evils. They were known as Voluntary Organizations. They did not support any political party or contest elections. They did not want to work in political parties. They discovered that direct interference was better than seeking political solutions to problems.

They also believed that such interventions would help the democratic government . Therefore they we known as non-political movements. They worked in urban and rural areas. But when more and more money came from outside, some of these groups became weak.

It is the dissatisfaction among people that causes them to organize in a non-political manner to find solutions to their problems. Even after 30 years of independence, neither the government nor the party was able to solve some democratic problems. In the 1970s, women, students, subalterns, peasants, etc. realized that politics wouldn’t solve their problems. Therefore they rallied under various social organizations and made their demands.

 The presence of social organizations thus became very much felt. Most of these organizations were formed against exploitation of Nature, inequality, exploitation, social evils, alcohol and such things. Women took a major role in all these. Chipko Movement, Dalit Panthers, Anti Arrack Movement, Narmada Bachao Andolan, National Fish Worker’s Union etc. are some such organizations that gained international attention.

Given T.S.A. of a cube 6l² = 1350

I² = 1350/6

I² = 225

∴ l =√225 = 15m

∴ Volume of the cube = l³

= 15 × 15 × 15 

= 3375 m³

(i) Given f(x) = 9x² + 12x + 2 ….(1) 

f'(x) = 18x + 12 …(2) 

f”(x) = 18 > 0 ……(3) 

⇒ f(x) attains minimum 

f'(x) = 0 ⇒ 18x+ 12 = 0 ⇒ x = -\(\frac{2}{3}\)

& f”(-\(\frac{2}{3}\) )18 > 0 ⇒ f(x) is minimum & the minimum value is 

f(-\(\frac{2}{3}\)) = 9\(\frac{4}{9}\) + 12(-\(\frac{2}{3}\)) + 2 

= 4 – 8 + 2 = -2 

(ii) f(x) = 2x³ – 15x² + 36x + 10 …….(1) 

f‘(x) = 6x² – 30x + 36 = 6 (x² – 5x + 6) ……..(2) 

f”(x) = 12x – 30 …..(3) 

f'(x) = 0 ⇒ x 2 -5x + 6 = 0 

⇒ (x – 3)(x – 2) = 0 ⇒ x = 3 or 2 

when x = 3 f “(x) = 12x – 30 

f“(3) = 36 – 30 = 6 > 0 

⇒ f(x) has minimum 

Minimum value is f(3) = 2(3)³ – 15(3)² + 36(3) + 10

f(3) = 54 – 135 + 108 + 10 = 37 

when x = 2, f”(2) = 24 – 30 = -6 < 0 

⇒ f(x) has maximum 

maximum value is f(2) = 2(2)³ – 15(2) + 36(2) + 10 f(2) = 16 – 60 + 72 + 10 = 38. 

(iii) Given f(x) = 2x³ – 21x² + 36x – 20 ….. (1) 

f'(x) = 6x² – 42x + 36 …… (2) 

= 6(x² – 7x + 6) 

f'(x) = 6(x – 1) (x – 6) = 0 ⇒ x = 1 or 6 

f”(x) = 12x – 42 … (3) 

when x = 1, f “(1) = 12 – 42 = -30 < 0 ⇒ f(x) is maximum 

maximum value is f(1) = 2 – 21 + 36 – 20 = -3 when x = 6, f“(6) = 72 – 42 = 30 > 0 ⇒ f(x) is minimum 

minimum value is f(6) = 2(6)3³ – 21 (6)² + 36(6) – 20 

f(6) = 432 – 756 + 216 – 20 = -128 

(iv) Given f(x) = 12x⁵ – 45x⁴ + 40 x³ + 6 ….(1) 

f'(x) = 60x⁴ – 180x³ + 120x² ….(2) 

= 60x² (x² – 3x + 2) = 60x² (x – 1) (x – 2) 

f‘(x) = 0 ⇒ 60x²(x – 1) (x – 2) = 0 ⇒ x = 0, 1, 2 f “(x) = 60 (4x³ – 6x + 4x) ……. (3) 

when x = 0, f”(x) = 0 ⇒ f(x) has neither maximum nor minimum 

when x = 1, f”(x) = -1 < 0 ⇒ f(x) has a maximum & maximum value is 

f(1) = 12 – 45 + 40 + 6 = 13 

When x =2 f”(x) = 4 > 0 

∴ f(x) has a minimum 

minimum value is f(2) = 12(32) – 45(16) + 40(8) + 6 

f(2) = 384 – 720 + 320 + 6 = -10.

For x > 0

Modulus will open with + sign

f(x) = +x

⇒ f’(x) = +1 which is < 0

for x < 0

Modulus will open with -ve sign

f’(x) = -x = > f’(x) = -1 which is > 0

hence f(x) is increasing in x > 0 and decreasing in x < 0

f(x) = ln(x)

f’(x) = 1/x

for x<0

f’(x) = -ve → increasing

for x>0

f’(x) = +ve → decreasing

f(x) in increasing when x>0 i.e x∈(0,∞)

Domain of function is R.

f’(x) = 2x

for x>0 f’(x)>0 i.e. increasing

for x<0 f’(x)<0 i.e. decreasing

hence it is neither increasing nor decreasing in R

Answer is : D. (-π/2, π/2)

Given: f(x) is sin x

∴ f’(x) = cos x

⇒ f’(x) = cos x

= 0

⇒ for x ∈ (-π/2, π/2)

f’(x) is increasing

∴ f(x) is increasing in (-π/2, π/2).

Correct option is  D) 6

Correct option is  D) 55

Correct option is  D) 280

Length= 20 

Breadth= 14 

Area of the rectangle A = l × b 

= 20 × 14 = 280

C) π (R² – r² ) 

Correct option is  C) πr²

Correct option is  C) 24

Correct option is  B) 6

Correct option is  A) \(\frac{1}{2}\)d₁d₂

Here, length of the rectangle (l) 

= Half of the perimeter of circle 

= πr 

breadth of the rectangle (b) 

= radius of circle = r 

We know that the area of the rectangle 

= l × b = πr × r (∵ l = πr, b = r) 

= πr² – Area of the circle. 

So, the area of the circle A = πr² 

Now we solve above problem, 

where ‘r’ = 7m 

Area of flower bed = πr²

= \(\frac {22}7\) × 7 × 7

= 22 × 7 

= 154 sq.m 

Number of plants per sq.m = 4 

Number of plants for 154 sq.m 

= 154 × 4 = 616 plants.

So, Headmaster needs 616 plants for the flower bed.

(a) Mrs. Packletide wished to shoot a tiger and get her pictures published.

(b) This was in order to prove herself superior to Loona Bimberton who had recently obtained a tiger-skin and couldn’t stop boasting about it. 

(c) The goat had died of the gunshot. The tiger had merely died of a heart failure caused by the sound of the gun shot.

(d) Louisa Mebbin blackmailed Mrs. Packletide into buying her the weekend cottage or else she would tell Loona Bimberton that it was not the tiger but a mere goat that Mrs. Packletide had shot.

Ribosome’s are called the ribonucleoprotein particles in a cell. They are called so, because they are formed by association of both RNA and protein. They suspend freely in the cytoplasm and gets stuck to the walls of endoplasmic reticulum as they get the signal from the nucleus. After the signal they carry out the process of protein synthesis via translation.
