y = 10 months 1 day

Required

How much older is Uma

To do this, we simply calculate the difference (d) in their ages:

This gives:

d = [12 years 9 months 5 days] - [10 months 1 day]

Collect like terms

d = [12 years 9 months - 10 months] + [5 days - 1 day]

d = [11 years 11 months] + 4 days

d = 11 years 11 months 4 days
