Suppose, the age of the son six year before was x

∴ mother’s age six year before was x² 

∴ present age of the son is (x + 6) and

present age of the mother is (x² + 6)

Three years hence, son’s age will be (x + 9) and mother’s age will be (x² + 9) by given condition,

x2 + 9 = 3(x + 9)

∴ x² - 3x + 9 - 27 = 0

∴ x² - 3x - 18 = 0 

∴ (x - 6) (x + 3) = 0

∴ x = 6 or x = -3

But age cannot be negative ∴ x ≠ -3

∴ son’s present age = x + 6 = 6 + 6 = 12 years.

mother’s present age = x² + 6 = 36 + 6 = 42 years.

Given:

The score of the students 92, 84, 75, 115, 99, 129, 119, 72, 109

Formula used:

When N is odd

Median = [(N + 1) ÷ 2]th term

Calculation

Arrange the score in ascending order,

72, 75, 84, 92, 99, 109, 115, 119, 129

Total number = 9

Then (9 + 1) ÷ 2

10 ÷ 2 = 5^th number = 99 

Correct answer is (c) Lower class limit is included

iv Looking after children 

v Plantation

1. India 

2. public places 

3. bus stands 

4. railway stations 

5. road crossings 

6. miserable 

7. weak 

8. general public.

We have given that sum of zeroes(S)= -3

and product of zeroes(P) = 2

so the quadratic polynomial p(x)= k(x² - Sx +P)

p(x) = k(x² - (-3)x + 2)

p(x) = k(x² + 3x + 2)

where  k  is any non-zero real number

Given:

Cloth length = 105(3/4) = 423/4 m

1(5/4) meter of cloth required to stitch a skirt.

Concept Used:

Concept of Unitary Method:-

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Calculations:

Number of skirt = (423/4)/(9/4) = 47

∴ Number of skirts can be stitched with 105 m of cloth is 47 skirts.

Given:

We have to find the number from the given options which have the square root rational.

Concept:

Unit digit and option trial method

Calculation:

We know that,

1² = 1

2² = 4

3² = 9

4² = 16

5² = 25

6² = 36

7² = 49

8² = 64

9² = 81

10² = 100

11² = 121

12² = 144 ...

and so on.

From the above, we can conclude that the unit digit of the square of a rational number will be one of 0, 1, 4, 5, 6, and 9

Among the given options only 34225 has the unit digit which satisfies the condition.

∴ Our desire number is 34225 which have the square root rational.

Yes, I agree that the poem ends in a note of wistful hope and prayer. The poet is requesting sleep to come to him. She has been running away for three nights in succession. He hopes she will listen to his entreaty and come to him this night.

Concept:

The difference of any three-digit number by its reversing number is always an exact product of 9 So, it is divisible by 9.

Calculation:

Let 100x + 10y + z be the number its reverse is 100z + 10y + x

Difference of the number will be

⇒ (100z + 10y + x) − (100x + 10y + z)

⇒ (100 − 1)z + (10 − 10)y + (1 − 100)x

⇒ 99z − 99x = 99(z − x)

So the difference of any three-digit number with its reverse number is divisible by 9 then the remainder is 0

∴ Remainder is 0

The poem is a sonnet. A sonnet is a poem of 14 lines with a strict pattern of rhyme and rhythm. There are different forms of the sonnet but they share some common things which include: a key idea, its proper development and a conclusion with a twist. A sonnet is divided into 2 parts. The first 8 lines are called an octave and the last 6 lines are called a sestet.

Dear Manju,

Hope you celebrated the Pongal festival with great joy. I went to my village for the festival holidays this time. It was the most joyous and memorable period of my life. I shall never forget this. You live in city and for you a festival means a holiday and you can wake up late. Then eat all the delicacies prepared by your mum and go for a new released movie or watch television at home. Here in village, they gather in a common place and celebrate. All of them rise early and actively participate in the rituals. All the ladies make pongal and offer it to Sun God as a mark of thanksgiving.

On the third day of festival, we went to fair and played on giant wheel and merry-go-round. We ate lots of fresh made native delicacies like raw mango with chilli powder and salt, palmyra sprout, vada of different varieties, appam, etc. Then we watched the dancers performing folk dances. We also went to the river, to swim and then bathe in the water. Since I didn’t know swimming, I just took a bath. Time was spent observing and being with nature. It was full of fun! The joy of celebrating festivals in a village is truly unforgettable

Yours friendly, Deepa

Given:

Anita and Batuk undertake a project worth = Rs. 27000

Anita alone can do the work = 10 days

Calculation:

Anita can do 10% of work in a day.

Anita has worked 6 days in total. And so, has Batuk.

Anita completed 60% work in 6 days and Batuk did 40% of the work in 6 days

Efficiency of Anita and Batuk = 6 : 4

∴ Batuk’s share = 4/10 × 27000

⇒ 4 × 2700

⇒ Rs. 10800

The share of Batuk in the earnings is Rs. 10800.

Given:

C is 20% more efficient than B,

let ratio of their efficiency be 6 : 5 

C is 50% more efficient than A,

let ratio of their efficiency be 2 : 3 

We know that if the ratio of efficiency is x : y  then the ratio of time taken will be y : x

Ratio of Days, C :  B : A  = 10 : 12 : 15

Let the total units to be produced be LCM(10,12 & 15) = 60 units

⇒ C’s 1 day work = 6 units

⇒ B’s 1 day work = 5 units

⇒ A’s 1 day work = 4 units

⇒ B alone can do work in = 60/5= 12

According to question

12 represents 72 days

⇒ 1 represents = 72/12= 6 days

So A ,B and C together can complete it in = (60/15) × 6  days= 24 days

Given:

A and B = 10 days

A/B = 5/3

Calculation:

1 day work of A : 1 day work of B = 5 : 3

⇒ Let the A work be 5X and B work be 3X

⇒ 5X + 3X = 1/10

⇒ 8X = 1/10

⇒ X = 1/80

⇒ A’s 1 day of work = 5 × (1/80)

Given:

A can do a certain job in 12 days.

B is 60% more efficient than A.

Formula used:

work = efficiency × days

Calculation:

Let efficiency of A be 100.

The efficiency of B will be 160.

Ratio of efficiency A and B = 100 : 160 = 5 : 8

Total work = efficiency ratio of A × total days taken by A to finish work

⇒ 5 × 12 = 60 unit

Time taken by B to finish work = total work/efficiency ratio of B

⇒ 60/8 = \(7\frac{1}{2} \) days

∴ B will finish the job in \(7\frac{1}{2} \) days.

Given:

Sharman is 20 percent less efficient than Vivek

Vivek can make a helmet alone in 20 days

Formula used:

The efficiency of a person is the inverse of the time taken

Calculation:

According to the question,

Per day efficiency of Vivek for making the helmet = 1/20

⇒ Sharman's per day efficiency for making the helmet = (80/100) × (1/20) = 0.8 × (1/20) = 1/25

∴ Sharman can make the helmet in 25 days.

Given:

The efficiency of A = 20% more efficiency of B

The efficiency of C = 60% more efficiency of D

The efficiency of B = 40% more efficiency of D

Total wages = ₹ 227200

Formula used:

Entire wages = Total number of days × Wages of 1 day of any person

Calculation:

The ratio of efficiency of A to B = 6 : 5,

The ratio of efficiency of C to D = 8 : 5

The ratio of efficiency of B to D = 7 : 5

After combining the ratio we get

The ratio of efficiency of A, B, C and D = 42 : 35 : 40 : 25

Share of C = 40 units

Total share = 42 + 35 + 40 + 25

⇒ 142 units

According to the question,

142 units = ₹ 227200

⇒ 1 unit = ₹ 1600

Share of C = 40 × 1600

⇒ ₹ 64000

∴ The share of C will be ₹ 64000.

I. 2X² – 74X + 420 = 0

⇒ X² – 30X – 7X + 210 = 0      ----(∵ taking 2 as common)

⇒ X(X – 30) – 7(X – 30) = 0

⇒ (X – 30)(X – 7) = 0

∴ The Value of X is 7, 30

II. 2Y² – 94Y + 560 = 0

⇒ Y² – 40Y – 7Y + 280 = 0      ----(∵ taking 2 as common)

⇒ Y(Y – 40) – 7(Y – 40) = 0

⇒ (Y – 7)(Y – 40) = 0

∴ The Value of Y is  7, 40

Hence, no relation can be established between X and Y.

Correct option is C) wondered

Given:

Time taken by A to complete the work = 5 days

Time taken by B to complete the work = 10 days

Total amount = ₹ 20000

Concept used:

Time ∝ 1/efficiency

Total wages = Person’s one-day work × Working days

Calculation:

Amount to be distributed = 20000 × (60/100) = ₹ 12000

Time taken by A = 5 days

Time taken by B = 10 days

⇒ One day work of A = 1/5

⇒ One day work of B = 1/10

⇒ Ratio of income = 1/5 : 1/10 = 2 : 1

⇒ Share A will get = (12000/3) × 2

∴ A share is ₹ 8000
