38.

When Rahul was born, his father was 32 years older than his brother and his mother was 25 years older than his sister. If Rahul's brother is 6 years older than him and his mother is 3 years younger than his father, how old was Rahul's sister when he was born ?

 [A]. 7 years [B]. 10 years [C]. 14 years [D]. 19 years

Explanation:

When Rahul was born, his brother's age = 6 years; his father's age = (6 + 32) years = 38 years, his mother's age = (38 - 3) years = 35 years; his sister's age = (35 - 25) years = 10 years.

 Imran Ali said: (Sep 17, 2014) 1st we see what is require. Rahul's sister age =? Given, Rahul's brother age = 6. Rahul's father is 32 years older than his brother. Hence, 6+32=38 is Rahul's father age. Rahuls mother is 3 years younger than his father. Hence, 38-3 is Rahul's mother age, Now, Rahul's sister age = 35-25 =10. Hence Rahul's sister age is 10 years. Thanks.

 Imran Ali said: (Oct 18, 2014) Step one: Rahul Sister Age = S. Given, F = 32+B ------ 1. M = 25+S ------ 2. F = M+3 -------- 3. B = 6 -------- 4. Put value of B from 4 in 1, we get. F = 38. Put F in 3, We get M. M= 35. Put value of M in 2 we get. S = 10. I hope now it is clear.
