Answer 1

Given : The ratio of the present ages of Radha and her father is 4:7 .

At the time of Radha's birth her father was 24 years.

To Find : the present ages of Radha and her father​

Solution:

The ratio of the present ages of Radha and her father is 4:7 .

Assume that Radha present age = 4x  years

Then Father present age = 7x years

At the time of Radha's birth her father was 24 years.

=> Father is 24 year older than Radha

Hence 7x = 4x + 24

=> 3x = 24

=> x = 8

Radha present age = 4x = 4(8) = 32 years

Then Father present age = 7x = 7(8) = 56 years

Present ages of Radha and her father​ are 32 and 56 years respectively

Assume that Radha present age=4x.

Then Father present age = 7x years.

At the time of Radha's birth her father was 24 years.

=> Father is 24 year older than Radha.

Hence 7x = 4x + 2

Radha present age = 4x = 4(8) = 32 years.

Then Father present age = 7x = 7(8) = 56 years.
