A. 
3 times 

B. 
5 times 

C. 
4 times 

D. 
2 times 
See Answer & Explanation
Lets Discuss
Correct answer is : D
Explanation Assume that Sunil's present age = x. Then father's present age = 3x + x = 4x. After 8 years, father's age = 2½ times of Sunils' age. => (4x+8) = 2½(x+8). => 4x + 8 = (5/2)(x + 8). => 8x + 16 = 5x + 40. => 3x = 40  16 = 24. => x = 24/3 = 8. After further 8 years, Sunil's age = x + 8 + 8 = 8 + 8 + 8 = 24. Father's age = 4x + 8 + 8 = 4 × 8 + 8 + 8 = 48. Father's age/Sunil's age = 48/24 = 2.

Ten years ago, P was half of Q's age. If the ratio of their present ages is 3:4, what will be the total of their present ages? 

A. 
45 

B. 
40 

C. 
35 

D. 
30 
See Answer & Explanation
Lets Discuss
Correct answer is : C
Explanation Let the present age of P and Q be 3x and 4x respectively. Ten years ago, P was half of Q's age => (3x – 10) = 12(4x – 10) => 6x – 20 = 4x – 10 => 2x = 10 => x = 5 Total of their present ages = 3x + 4x = 7x = 7 × 5 = 35.

A man's age is 125% of what it was 10 years ago, but 8313% of what it will be after 10 years. What is his present age? 

A. 
70 

B. 
60 

C. 
50 

D. 
40 
See Answer & Explanation
Lets Discuss
Correct answer is : C
Explanation Let the age before 10 years = x Then, 125x/100 = x + 10.
=> 125x= 100x + 1000.
=> x = 1000/25 = 40.
Present age = x + 10 = 40 +10 = 50.

Lets Discuss
Correct answer is : B
Explanation Let the present age of the son = x years Then present age the man = (x+24) years Given that in 2 years, man's age will be twice the age of his son => (x+24) +2 = 2(x+2) => x = 22

Present ages of Kiran and Syam are in the ratio of 5 : 4 respectively. Three years hence, the ratio of their ages will become 11 : 9 respectively. What is Syam's present age in years? 

A. 
24 

B. 
26 

C. 
27 

D. 
28 
See Answer & Explanation
Lets Discuss
Correct answer is : A
Explanation Ratio of the present age of Kiran and Syam = 5 : 4. Let the present age of Kiran = 5x . Present age of Syam = 4x. After 3 years, ratio of their ages = 11:9. => (5x + 3) : (4x + 3) = 11 : 9. => 9(5x + 3) = 11(4x + 3). => 45x + 27 = 44x + 33. => x = 3327 =6. Syam's present age = 4x = 4×6 = 24.
