5.	what number should be added to each of the numbers 94, 24, 100 and 26, so that the resulting numbers are in continued proportion
Answer» Given: The nunmbers 94, 24, 100 and 26. To find: What number should be added to each of the numbers 94, 24, 100 and 26, so that the resulting numbers are in continued PROPORTION Solution: LET the number added be x. The numbers are 94+x,24+x,100+x and 26+x. As these numbers are in continued proportion. so we have, PRODUCT of extremes = product of means (94+x)(26+x) = (24+x)(100+x) 24 44+26x+94x+x^2 = 2400+100x+24x+x^2 2444+120x+x^2 = 2400+124x+x^2 2444 -2400 +x^2 - x^2 = 124x-120x 44 = 4x x= 44/4=11 Therefore, 11 must be added to each number.

what number should be added to each of the numbers 94, 24, 100 and 26, so that the resulting numbers are in continued proportion

Answer»

Given:

The nunmbers 94, 24, 100 and 26.

To find:

What number should be added to each of the numbers 94, 24, 100 and 26, so that the resulting numbers are in continued PROPORTION

Solution:

LET the number added be x.

The numbers are 94+x,24+x,100+x and 26+x.

As these numbers are in continued proportion.

so we have, PRODUCT of extremes = product of means

(94+x)(26+x) = (24+x)(100+x)

24 44+26x+94x+x^2 = 2400+100x+24x+x^2

2444+120x+x^2 = 2400+124x+x^2

2444 -2400 +x^2 - x^2 = 124x-120x

44 = 4x

x= 44/4=11

Therefore, 11 must be added to each number.

Answer»

GIVEN : रोहित और मोहित कि वर्तमान आयु का अनुपात क्रमश 5 : 7 है | मोहित का पुत्र कि वर्तमान आयु और रोहित के पुत्र कि वर्तमान आयु का अनुपात क्रमश 3 : 2 है

To find : रोहित के पुत्र और मोहित के पुत्र की आयु क बीच का अन्तर ज्ञात करें

Solution:

रोहित और मोहित कि वर्तमान आयु का अनुपात क्रमश 5 : 7 है

रोहित कि वर्तमान आयु = 5 A

मोहित कि वर्तमान आयु = 7A

मोहित का पुत्र कि वर्तमान आयु और रोहित के पुत्र कि वर्तमान आयु का अनुपात क्रमश 3 : 2 है

मोहित का पुत्र कि वर्तमान आयु = 3B

रोहित के पुत्र कि वर्तमान आयु = 2B

रोहित के पुत्र और मोहित के पुत्र की आयु क बीच का अन्तर = 3B - 2B = B

जब मोहित की आयु रोहित की वर्तमान आयु के समान थी => 2A वर्ष पहले

तो मोहित के पुत्र का जन्म हुआ था |

=> 3B = 2A

=> A/3 = B/2

रोहित के विवाह के समय रोहित की आ यु तथा मोहित की आयु क बीच का अनुपात क्रमश 5 : 8 था

विवाह X वर्ष पहले

=> (5A - X) /( 7A - X) = 5/8

=> 40A - 8X = 35A - 5X

=> 5A = 3X

=> X = 5A/3

| रोहित के पुत्र का जन्म रोहित के विवाह के 3 वर्ष बाद हुआ था

=> X - 3 = 2B

=> 5A/3 - 3 = 2B

=> 5B/2 - 3 = 2B A/3 = B/2

=> 5B - 6 = 4B

=> B = 6

रोहित के पुत्र और मोहित के पुत्र की आयु क बीच का अन्तर = 6 वर्ष

Answer» AnswEr:- Three digits number = 852 $\rule{200}{2}$ Let the three digits of the number be a, a + d & a + 2d as they are in A.P ∴ Number = a + 10(a + d) + 100(a + 2d) Case 1:- ⇒ a + (a + d) + (a + 2d) = 15 ⇒ a + a + d + a + 2d = 15 ⇒ 3a + 3D = 15 ⇒ 3(a + d) = 15 ⇒ a + d = 15/3 ⇒ a + d = 5 [Eq.1] Case 2:- Number obtained by REVERSING digits:- ∴ Number = 100a + 10(a + d) + (a + 2d) According to question:- ⇒ [a + 10(a + d) + 100(a + 2d)] - [100a + 10(a + d) + (a + 2d)] = 594 ⇒ a + 10a + 10d + 100a + 200d - 100a - 10a - 10d - a - 2d = 594 ⇒ 111a + 210d - 111a - 12D = 594 ⇒ 198d = 594 ⇒ d = 594/198 ⇒ d = 3 Put this value in (Eq.1) ⇒ a + 3 = 5 ⇒ a = 5 - 3 ⇒ a = 2 $\rule{150}{1}$ ⋆ THREE DIGITS OF THE NUMBER:- ↠ First DIGIT = a = 2 ↠ Second digit = a + d = 2 + 3 = 5 ↠Third digit = a + 2d = 2 + 2(3)= 2 + 6 = 8 $\rule{150}{2}$ ⋆ THREE DIGITS NUMBER :- ⇒ Number = 2 + 10(2 + 3) + 100{2 + 2(3)} ⇒ Number = 2 + 10(5) + 100(8) ⇒ Number = 2 + 50 + 800 ⇒ Number = 852 Therefore, Three digits number = 852 .

23.

The digits of a positive integer, having three digits are in A. P and their sum is 15.The number obtained by reversing the digits is 594 less than the original number. Find the number

Answer»

AnswEr:-

Three digits number = 852

$\rule{200}{2}$

Let the three digits of the number be a, a + d & a + 2d as they are in A.P

∴ Number = a + 10(a + d) + 100(a + 2d)

Case 1:-

⇒ a + (a + d) + (a + 2d) = 15

⇒ a + a + d + a + 2d = 15

⇒ 3a + 3D = 15

⇒ 3(a + d) = 15

⇒ a + d = 15/3

⇒ a + d = 5 [Eq.1]

Case 2:-

Number obtained by REVERSING digits:-

∴ Number = 100a + 10(a + d) + (a + 2d)

According to question:-

⇒ [a + 10(a + d) + 100(a + 2d)] - [100a + 10(a + d) + (a + 2d)] = 594

⇒ a + 10a + 10d + 100a + 200d - 100a - 10a - 10d - a - 2d = 594

⇒ 111a + 210d - 111a - 12D = 594

⇒ 198d = 594

⇒ d = 594/198

⇒ d = 3

Put this value in (Eq.1)

⇒ a + 3 = 5

⇒ a = 5 - 3

⇒ a = 2

$\rule{150}{1}$

⋆ THREE DIGITS OF THE NUMBER:-

↠ First DIGIT = a = 2

↠ Second digit = a + d = 2 + 3 = 5

↠Third digit = a + 2d = 2 + 2(3)= 2 + 6 = 8

$\rule{150}{2}$

⋆ THREE DIGITS NUMBER :-

⇒ Number = 2 + 10(2 + 3) + 100{2 + 2(3)}

⇒ Number = 2 + 10(5) + 100(8)

⇒ Number = 2 + 50 + 800

⇒ Number = 852

Therefore,

Three digits number = 852 .

25.	The numerator of a fraction is 3 less than its denominator if 1is added to the denominator the fraction is decrased by 1/15find the fraction
Answer» AnswEr:- Fraction = 2/5 or 6/9 $\rule{200}{2}$ Case 1:- • NUMERATOR = Denominator - 3 Let the denominator be n & numerator be (n - 3) ∴ Fraction = (n - 3)/n Case 2:- • 1 added to denominator, fraction is DECREASED by 1/15 According to question:- ⇒ (n - 3)/(n + 1) = [(n - 3)/n] - 1/15 ⇒ (n - 3)/(n + 1) = [15(n - 3) - n]/15n ⇒ (n - 3)/(n + 1) = [15n - 45 - n]/15n ⇒ (n - 3)/(n + 1) = [14n - 45]/15n ⇒ 15n(n - 3) = (n + 1)(14n - 45) ⇒ 15n² - 45n = 14n² - 45n + 14n - 45 ⇒ 15n² - 45n = 14n² - 31n - 45 ⇒ 15n² - 14n² - 45n + 31n + 45 = 0 ⇒ n² - 14n + 45 = 0 ⇒ n² - 5n - 9n + 45 = 0 ⇒ n(n - 5) - 9(n - 5) = 0 ⇒ (n - 5)(n - 9) = 0 ⇒ n = 5 or n = 9 So, denominator of fraction = 5 or 9 . Numerator:- (when denominator is 5) ⇒ Numerator = n - 3 ⇒ Numerator = 5 - 3 ⇒ Numerator = 2 ∴ Fraction = 2/5 Numerator:- (when denominator is 9) ⇒ Numerator = n - 3 ⇒ Numerator = 9 - 3 ⇒ Numerator = 6 ∴ Fraction = 6/9 Therefore,as both fractions fulfills the desires of question:- Fraction is 2/5 or 6/9 .

25.

The numerator of a fraction is 3 less than its denominator if 1is added to the denominator the fraction is decrased by 1/15find the fraction

Answer»

AnswEr:-

Fraction = 2/5 or 6/9

$\rule{200}{2}$

Case 1:-

• NUMERATOR = Denominator - 3

Let the denominator be n & numerator be (n - 3)

∴ Fraction = (n - 3)/n

Case 2:-

• 1 added to denominator, fraction is DECREASED by 1/15

According to question:-

⇒ (n - 3)/(n + 1) = [(n - 3)/n] - 1/15

⇒ (n - 3)/(n + 1) = [15(n - 3) - n]/15n

⇒ (n - 3)/(n + 1) = [15n - 45 - n]/15n

⇒ (n - 3)/(n + 1) = [14n - 45]/15n

⇒ 15n(n - 3) = (n + 1)(14n - 45)

⇒ 15n² - 45n = 14n² - 45n + 14n - 45

⇒ 15n² - 45n = 14n² - 31n - 45

⇒ 15n² - 14n² - 45n + 31n + 45 = 0

⇒ n² - 14n + 45 = 0

⇒ n² - 5n - 9n + 45 = 0

⇒ n(n - 5) - 9(n - 5) = 0

⇒ (n - 5)(n - 9) = 0

⇒ n = 5 or n = 9

So, denominator of fraction = 5 or 9 .

Numerator:- (when denominator is 5)

⇒ Numerator = n - 3

⇒ Numerator = 5 - 3

⇒ Numerator = 2

∴ Fraction = 2/5

Numerator:- (when denominator is 9)

⇒ Numerator = n - 3

⇒ Numerator = 9 - 3

⇒ Numerator = 6

∴ Fraction = 6/9

Therefore,as both fractions fulfills the desires of question:-

Fraction is 2/5 or 6/9 .

Answer» Answer: Hey BUDDY here's ur answer sinAsinB - cosAcosB = 1 <--- given cosAcosB - sinAsinB = -1 <--- multiplies both sides by -1 cos(A+B) = -1 <--- angle addition FORMULA for COSINE A+B is an odd multiple of pi <--- cosine function is -1 at 180=pi, 540 = 3pi, 900=5pi, etc sin(A+B)=0 <-- SINE function is zero at odd multiples of pi sinAcosB + sinBcosA = 0 <--- angle addition formula for sine sinA/cosA + sinB/cosB = 0 <--- divides both sides by cosAcosB tanA + tanB = 0 <--- TAN = sin/cos

28. If sin a.sin ß-cosa.cosB =1, show that tan a+tan B=0.

Answer»

Answer:

Hey BUDDY here's ur answer

sinAsinB - cosAcosB = 1 <--- given

cosAcosB - sinAsinB = -1 <--- multiplies both sides by -1

cos(A+B) = -1 <--- angle addition FORMULA for COSINE

A+B is an odd multiple of pi <--- cosine function is -1 at 180=pi, 540 = 3*pi, 900=*5*pi, etc

sin(A+B)=0 <-- SINE function is zero at odd multiples of pi

sinAcosB + sinBcosA = 0 <--- angle addition formula for sine

sinA/cosA + sinB/cosB = 0 <--- divides both sides by cosA*cosB

tanA + tanB = 0 <--- TAN = sin/cos

The height of a cone is 20m and its baseradius is 50cm - Find the curned surfacearea and the total surface areaof the cone.

Answer»

Answer:

GIVEN height= 20cm ,

BASE radius = 50cm ,

To FIND: CSA of cone and TSA of cone

Solve : CSA of cone = πrl

= 22\7 x 50 x 20

3142.8..CM2

and TSA of cone = πr(l+r)

= 22\7 x 50 ( 20+50 )

= 22\7 x 50 ( 70)

= 1100cm2
