Answer»

Answer:

Step-by-step explanation:

Let Amit's age be X

Let Vaibhav's age be Y

According to Questions,

X=Y+5-(1)

After FOUR years,

4+X/4+Y=5/4

Using (1)

Y+5+4/Y+4=5/4

Y+9/Y+4=5/4

Cross Multiplication,

5(Y+4)=4(Y+9)

5Y + 20= 4Y + 36

Y=16

Amit's age= Y+5

=21

Vaibhav's age = 16
