Question

shobha is 3 year older than his brother suresh. 6 years ago shobha's age was 4 times the age of suresh. what is their present age

Answer 1

Let shobha age be x
her brother suresh age =x-3
6 years ago their ages
shobha=x-6,suresh=x-3-6=x-9
given shobha age was 4 times the age of suresh
So 4(x-9)=x-6
4x-36=x-6
4x-x=-6+36
3x=30
x=30/3=10
So shobha age =10years
Suresh age=10-3=7years
