Question

Kathy is 8 years 4 months old. Her mother is 40 years 3 months old.
How old was her mother when Kathy was born?​

Answer 1

Answer:

31 years 11 months

Step-by-step explanation:

1 year = 12 months

Kathy's age = (8 * 12) + 4 = 96 + 4 = 100 months

Mother's age = (40 * 12) + 3 = 480 + 3 = 483 months

Mother's age when Kathy was born = 483 - 100 = 383 months

When we divide 383 by 12 , we get 31 as quotient and 11 as remainder.

So, Kathy's mother was 31 years 11 months when Kathy was born.
