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 ?
Answer: Option
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.

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.

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.

Let.
Rahul was x. so his father x + 32.
Sister was y, so her mother y + 25.
Now, x+32-y-25 = 3.
=> x-y = 10 answer.
Rahul was x. so his father x + 32.
Sister was y, so her mother y + 25.
Now, x+32-y-25 = 3.
=> x-y = 10 answer.
