• 1) 18
• 2) 25
• 3) 15
• 4) 20
Ans.   D
Explanation :
Sachin's age today = 30 years. Sachin's age 10 years back = 20 years. Ajay's age 10 years back = 10 years. Ajay's age today =20 years

12) In 10 years, A will be twice as old5as B was 10 years ago. If A is now 9 years older than B, the present age of B

• 1) 35
• 2) 37
• 3) 39
• 4) 41
Ans.   C
Explanation :
Let B's age = x years. Then, As age = (x+ 9) years. (x+9+10)=2(xâ€”10) hence x=39. Present age of B = 39 years

13) Ten years ago A was half of B in age. If the ratio of their present ages is 3 : 4, what will be the total of their present a

• 1) 30
• 2) 35
• 3) 37
• 4) 41
Ans.   B
Explanation :
Let A's age 10 years ago = x years. Then, B's age 10 years ago = 2x years. (x + 10) / (2x+ lO) = 3/4 => x = 5. So, the total of their present ages =(x + 10 + 2x + 10) = (3x + 20) = 35 years.

14) Sushil was thrice as old as Snehal 6 years back. Sushil will be times as old as Snehal 6 years hence. How old is Snehal to

• 1) 12
• 2) 16
• 3) 18
• 4) 24
Ans.   A
Explanation :
Let Snehals age 6 years back = x. Then, Sushils age 6 years back = 3x. (5/3) * (X + 6 + 6) = (3X + 6 + 6) So 5(x+ 12) = 3(3x+ 12), so x=6. Snehal Age = (x+ 6) years = 12 years

15) Six years ago, the ratio of the ages of Kunal and Sagar was 6:5, Four years hence, the ratio of their ages will be 11:10. What is Sagar age at pres

• 1) 10 years
• 2) 12 years
• 3) 14 years
• 4) 16 years
Ans.   D
Explanation :
Let six years ago the age of Kunal and Sagar are 6x and 5x resp. then, \begin{aligned} => \frac{(6x+6)+4}{(5x+6)+4} = \frac{11}{10} \end{aligned} \begin{aligned} <=> 10(6x+10) = 11(5x+10) \end{aligned} \begin{aligned} <=> 5x = 10 => x = 2 \end{aligned} So Sagar age is (5x+6) = 16

16) Average age of A and B is 24 years and average age of B, C and D is 22 years. The sum of the ages of A, B, C and D

• 1) 90
• 2) 98

• 1) 25
• 2) 30
• 3) 45
• 4) 60
Ans.   B
Explanation :
Let their ages 10 years ago is x, 2x and 3x years. 10 + 2x + 10 + 3x + 10 = 90 hence x= 10 Bâ€™s present age = (2x + 10) =30 years

18) A man is 24 years older than his son. In two years, his age will be twice the age of his son. The present age of his son

• 1) 20 years
• 2) 21 years
• 3) 22 years
• 4) 24 years
Ans.   C
Explanation :
Let the son's present age be x years. Then, man's present age = (x + 24) years => (x + 24) + 2 = 2(x + 2) => x + 26 = 2x + 4 So, x = 22

19) Ratio of ages of three persons is 4:7:9, Eight years ago, the sum of their ages was 56. Find their present ag

• 1) 16,35,36
• 2) 12,28,36
• 3) 16,28,27
• 4) 16,28,36
Ans.   D
Explanation :
Let the present ages are 4x, 7x, 9x. => (4x-8) + (7x-8) + (9x-8) = 56 => 20x = 80 => x = 4 So their present ages are: 16,28,36

20) A man is 24 years older than his son. In two years, his age will be twice the age of his son. The present age of this son
