Question

Vijay is older than his sister Sheema by 12 years. 4 years ago Vijay was 4 times as old as his sister. find their present age

Answer 1

Let Sheema's age be X,
Now , Vijay's age will be, X+12,

4 years ago,
According to data,
(X+12)-4 = 4(X-4)

=> X+8 = 4X-16,
=> 24 = 3x ,

=> X = 8,

so Sheena's present age = 8,

Vijay's present age = 8+12 = 20,

Hope you understand !
