Question

The ages of amit and archana are in ratio 4:5. If amit is 4 years 8 months old, find the age of archana

Answer 1

1 yr = 12 months...so 4 yrs = (12 x 4) = 48 months + 8 months = 56 months

4/5 = 56/x
cross multiply
4x = 280
x = 280/4
x = 70 months = 5 yrs and 10 months

Answer 2

Convert 4 years 8 months into months=56 months
4+5=9
4/5 * X=56
x=280/4=70
therefore to find archana's age
5/9*70=39 months=3 years and 3 months
