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
