Anyone solve this question please please ​

Answer 1

Let Riya's present age be x.

Radha's age = 4x

After 5 years

Riya's age = x+5

Radha's age = 4x + 5

⇒(x+5) + (4x+5) =80 years

⇒x+5+4x+5 = 80

⇒5x+10 = 80

⇒5x = 80-10

⇒5x = 70

⇒x = $\frac{70}{5}$

⇒ x= 14 years

Riya's present age = x = 14 years.

Radha's present age = 4x = 4×14 = 56 years
