Answer 1

let radha age be x
her cousin age=x+19
After 5 years their ages
Radha=x+5 Her cousin=x+19+5=x+24
Their age ratio=2:3
x+5:x+24=2:3
3(x+5)=2(x+24)
3x+15=2x+48
3x-2x=48-15
x=33
Radha present age=33years
Her cousin present age=33+19=52

Answer 2

Answer:

Step-by-step explanation:

Let Radha's age be = x

Cousin's Age = x+19

After 5 yrs.

Radha's age = x+5

Cousin's age = x+19+5 = x+24

x+5 : x+24 = 2 : 3

(BY CROSS MULTIPLY)

3 (x+5) = 2 (x+24)

3x+15 = 2x+48

3x-2x = 48-15

x=33

Presently/Answer

Radha's age = 33

Cousin's age =33+19=42
