1) 14
2) 22
3) 18
4) 20
Answer: 3
Solution: Let father present age is X, Then present age of son will be (30-X).
Mother’s age 6 years ago
(X-6)= (30-X-6)+18
X-6=42-X
2X= 48
X= 24
Therefore, Mother’s present age is 24 years. 6 years ago his age was 24-6 = 18years.
50. 4 years ago Jaipal age was 12 years more than the Sravani’s age then. If the sum of their present ages is 30 what was the age of Sravani 4 years ago?

3) 15
4) 11
Answer:1
Solution:
Let Jaipal present age is X, Then present age of sravani will be (30-X).
Jaipal’s age 4 years ago
(X-4)= (30-X-4)+12
X-4=38-X
2X= 42
X= 21
Therefore, Jaipal’s present age is 21 years. Sravani’s present age will be 30-X = 30-21= 9 years
