Answer 2

Answer:

The ratio of the age of father and his son after 5 years is 11:4.

Step-by-step explanation:

It is given that the ratio of the age of father and his son is 4:1.

Let their present age is 4x and x respectively.

It is given that the product of their present age is 196.

$4x\times x=196$

$4x^2=196$

$x^2=49$

$x=7$

The value of x is 7.

The present age of father and son is 28 and 7.

$28+5=33$

$7+5=12$

The age of father and son after 5 years is 33 and 12.

$\frac{33}{12}=\frac{11}{4}$

Therefore the ratio of the age of father and his son after 5 years is 11:4.
