Question

Ritu is now 4 times as old as his brother raju in 4 years time her age will be twice of raju's age what are their present ages

Answer 1

Raju's age = a

Ritu's age = 4a

After 4years

Raju's age = a + 4

Ritu's age = 2(a+4)

4a + 4 = 2a + 8

2a = 4

a = 2

Raju's age = 2

Ritu's age  = 8
