Rose is 12 years 6 months old and Patty is 12 years 8 months old. Their total age is___________.

The correct answer is: 25 years 2 months

Rose's age = 12 years 6 months
Patty's age = 12 years 8 months
Total of their age = 24 years 14 months = 24 years 1 year 2 months
= 25 years 2 months

Given, rose is 12 years and six months old and Patty is 12 years eight months old .To find the total age will have to add the ages of rose and Patty. After addition, we get 24 years and 14 months. We know that there are 12 months in a year which implies that in 14 months, there will be one year and two months. Hence, the resultant answer is 25 years and two months.
