Question

The present age of Ravi and Menu are in the ratio 5:7. After 4 years their age will be in the ratio 3:4. Find their ages.​

Answer 1

Answer:

Let the present age of Ravi = 5y years

Let the present age of Meenu = 7y years

According to condition:

5y +4 / 7y+4 =3/4

= 20y +16= 21y +12

=20y – 21y =12- 16

= -y = -4

= y = 4

Ravi’s present age = 5y = 5 x 4 = 20 years

Meenu’s present age = 7y = 7×4 = 28 years
