270+ Problems on Ages Questions

51. A’s age is 125% of B’s age and the average age of A, B, C and D is 32 years. Difference between the ages of C and D is 13 years and the ratio of the ages of A to C is 5:7. If D is elder than C, then what is the present age of D?

A की आयु B की आयु का 125% है और A, B, C और D की औसत आयु 32 वर्ष है। C और D की आयु के बीच में अंतर 13 वर्ष है और A से C की आयु का अनुपात 5: 7 है। यदि D, C से बड़ा है, तो D की वर्तमान आयु क्या है?

A. 42 years
B. 45 years
C. 48 years
D. 51 years
E. None of these

Option “C” is correct.

Given that, A=125/100 * B

A=5/4 * B

A/C=5/7

D – C=13

A + B + C + D=32 * 4=128

A:B:C=5:4:7

D – 7x=13

D=13 + 7x

5x + 4x + 7x + 13 + 7x=128

x=5

Thus, D’s age=7 * 5 + 13=48 years

52. Four years after, the ratio of the ages of Shon and Surya is 2:3 and 7 years ago, Shon’s age is 52% of Surya’s age. What is the sum of the present ages of Shon and Surya?

चार साल बाद शॉन और सूर्या की आयु का अनुपात 2: 3 है| और 7 साल पहले शॉन की आयु, सूर्या की आयु का 52% है। शॉन और सूर्या के वर्तमान आयु का योग क्या है?

A. 52 years
B. 54 years
C. 56 years
D. 58 years
E. None of these

Option “A” is correct.

Let the present age of Shon=x

Let the present age of Surya=y

(x + 4)/(y + 4)=2/3

3x + 12=2y + 8

3x – 2y + 4=0 ———(1)

(x – 7)=52/100 * (y – 7)

25x – 175=13y – 91

25x – 13y – 84=0 ———-(2)

(1) * 25 – (2) * 3

-11y =-352

y=32 years

From (1),

3x – 64 + 4=0

x=20 years

Hence x + y=32 + 20=52 years

53. Five years ago, the ratio of the ages of A to B is 2:1 and the present age of A is 20 years more than B. If C’s age is 20% more than the sum of the present age of A and B together, then what is C’s age after 8 years?

पाँच साल पहले A से B की आयु का अनुपात 2: 1 है और A की वर्तमान आयु B से 20 वर्ष अधिक है। यदि C की आयु A और B की वर्तमान आयु के योग की तुलना में 20% अधिक है, तो फिर 8 साल बाद C की आयु क्या है?

A. 90 years
B. 88 years
C. 94 years
D. 86 years
E. None of these

Option “E” is correct.

(A – 5)/(B – 5) = 2/1

A – 5 = 2B – 10

A – 2B = -5

A = B + 20

B + 20 – 2B=-5

B = 25

A = 25 + 20=45

C = 120/100 * (45 + 25)

= 84 years

After 8 years C’s age = 84 + 8=92

54. What is the present age of Simian, who is 9 years elder to Santhi and present age of Prasanth is double of the age of Santhi and average age of all the three persons together at present is 23 years?

सुभा की वर्त्तमान आयु क्या है, जो शांती से 9 वर्ष बड़ी है और प्रशांत की वर्तमान आयु शांती की आयु की दोगुनी है और वर्तमान में एक साथ तीनों व्यक्तियों की औसत आयु 23 वर्ष है?

A. 30 years
B. 18 years
C. 25 years
D. 28 years
E. None of these

Option “E” is correct.

Let the present age of Subha, Prasanth and Santhi is ‘x’, ‘y’ and ‘z’ respectively.

(x + y + z)/3 =23

(x + y + z) = 69…. (1)

y = 2z … (2) From (1) and (2):

x + 3z = 69….(3)

x – z = 9….(4)

From (3) and (3):

4x = 96

x = 24 years

55. If the product of the ages of Ragu and Sonu is 768 years and the sum of the ages of Ramu and Rinu is 75 years. Rinu age is 16 years, when Sonu was born. If the average of the ages of Ramu, Rinu and Sonu is 33 years, then what is the present age of Ragu?

यदि रागु और सोनू की आयु का गुणनफल 768 वर्ष है और रामू और रिनू की आयु का योग 75 वर्ष है। रिनू की आयु 16 वर्ष है जब सोनू का जन्म हुआ था। यदि रामू, रिनू और सोनू की आयु का औसत 33 वर्ष है, तो रागु की वर्तमान आयु क्या है?

A. 20 years
B. 27 years
C. 32 years
D. 38 years
E. Cannot be determined

Option “C” is correct.

Ramu + Rinu + Sonu=99

Rinu = Sonu + 16

Ramu + Rinu=75

Ramu + Sonu + 16=75

Ramu=59 – Sonu

59 – Sonu + Sonu + 16 + Sonu=99

Sonu=24 years

Ragu=768/24=32 years

56. There are 10 students in the class. The average age of first five students in the class is 25 years and then the average of next two students in the class is 30 years. If the remaining three student’s average age is 39 years, then what is the average age of the class?

कक्षा में 10 छात्र हैं। कक्षा में पहले पांच छात्रों की औसत आयु 25 वर्ष है और फिर कक्षा में अगले दो छात्रों की औसत आयु 30 वर्ष है। यदि शेष तीन छात्र की औसत आयु 39 वर्ष है, तो कक्षा की औसत आयु क्या है?

A. 30.2 years
B. 32.5 years
C. 36.4 years
D. 31.8 years
E. 39 years

Option “A” is correct.

Total age of the class = 5 * 25 + 2 * 30 + 39 * 3= 302

Required average = 302/10 = 30.2 years

57. Find the present age of Aathi. Aathi is 5 years older than Ambani and Ambani is 5 years older than Deena. 16 years ago, Aathi was 6 years older than twice the age of Deena at that time.

आथी की वर्तमान आयु ज्ञात करें। आथी, अंबानी से 5 साल बड़ी हैं और अंबानी, दीना से 5 साल बड़ी हैं। 16 साल पहले उस समय दीना की आयु की दोगुना की तुलना में आथी 6 साल बड़ी थी।

A. 25 years
B. 20 years
C. 30 years
D. 22 years
E. 28 years

Option “C” is correct.

Let the ages of Ambani, Aathi and Deena are A, B and C respectively.

As per the question,

B=A+ 5

A=C+ 5

=>B=C+ 10 —-  (i)

Also,

B-16 = 2(C-16) + 6

=> 2C – B = 10 —- (ii)

(i) + (ii) => 2C = C + 20

=> C = 20

=> B = 30 years

58. Ratio of the ages of Anu and Aditi is 3:8 and after 5 years, the ratio of the ages of Aditi to Ambi is 7:5. If the sum of the ages of Aditi, Ambi and Anu is 32 years, then what is the present age of Anu?

अनु और अदिति की आयु का अनुपात 3: 8 है और 5 वर्ष के बाद अदिति से अंबी की आयु का अनुपात 7: 5 है। यदि अदिति, अम्बी और अनु की आयु का योग 32 वर्ष है, तो अनु की वर्तमान आयु कितनी है?

A. 12 years
B. 15 years
C. 9 years
D. 3 years
E. None of these

Option “E” is correct.

Anu/Aditi = 3/8

Aditi + Ambi + Anu = 32

(Aditi + 5)/(Ambi + 5) = 7/5

7Ambi + 35 = 5Aditi + 25

3/8 Aditi + Aditi + (5Aditi – 10)/7 = 32

21Aditi + 56Aditi + 40Aditi – 80 = 32 * 56

117Aditi = 1872

Aditi = 16 years

Anu = 3/8 * 16 = 6 years

59. 8 years ago, the ratio of the ages of A and B is 4:5 and after 12 years, the difference between the ages of A and B is 7 years. What is the sum of the present age of A and B?

8 वर्ष पहले A और B की आयु का अनुपात 4: 5 हैं और 12 वर्ष के बाद A और B की आयु का अंतर 7 वर्ष है। A और B की वर्तमान आयु का योग क्या है?

A. 73 years
B. 75 years
C. 77 years
D. 79 years
E. None of these

Option “D” is correct.

(A – 8)/(B – 8)=4/5

5A – 40=4B – 32

5A – 4B=8—–(1)

(B + 12) – (A + 12)=7

B – A=7—-(2)

(1) + (2) * 4

A= 36 years

B=36 + 7=43 years

Sum=36 + 43=79 years

60. The average age of A, B, C and D is 42 years and the average age of B, C and D is 28 years. If the sum of the ages of A and B is 144 years and after 10 years, the ratio of the ages of B to C is 7:3, then what is the present age of D?

A, B, C और D की औसत आयु 42 वर्ष है और B, C और D की औसत आयु 28 वर्ष है। यदि A और B की आयु का योग 144 वर्ष है और 10 वर्ष के बाद B से C की आयु का अनुपात 7: 3 है, तो D की वर्तमान आयु क्या है?

A. 8 years
B. 7 years
C. 12 years
D. 5 years
E. None of these

Option “E” is correct.

A + B + C + D=42 * 4=168

B + C + D=28 * 3=84

A + B=144

A=168 – 84 = 84 years

B =144 – 84 = 60 years

C + D =168 – (84 + 60) = 24 years

After 10 years B’s age=60 + 10=70 years

C’s age after 10 years=70 * 3/70=30 years

Present age of C=30 – 10=20 years

D =24 – 20 = 4 years.
