Solution: Option a , Rupa's age is 24 years
Explanation : Ages of them are Meena=3x,Rupa=4x and Deepa=5x , So to find their ages we have to do as
Average of their ages = Sum /no
24=3x +4x+5x/3
24=12x/3
x=24×3/12
=6
Thus their ages are
Meena=3x=3×6=18 years
Rupa=4x=4×6=24 years
Deepa=5x=5×6=30 years
