Answer:

RAVI = 20 YEARS

MEENU = 28 YEARS

Step-by-step explanation:

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
