Bharti is older than Arti by 3 years. What will be the age of Arti after 3 years if sum of their ages is 12.*

Answer:

9 years

Answer 2

Answer:

Bharti age(B) - Arti age(A) = 3

Bharti age + Arti age =12

adding both

B-A+B+A=3+12

2B=15

B=7.5years

A = 12-7.5

A=4.5 years

After 3years Arti's age = 3+4.5

=7.5years
