Nice Question. I liked the language of this question.

We need to find the number of homes that were remodeled last year and the age of such remodeled homes is less than 10 years.Statement -1---> 62 percent of the homes in City X are less than 10 years old.

Insufficient because this statement does not tell what percent of these 10 years old houses were remodeled last year.Statement -2---> 32 percent of the homes in City X have been remodeled in the last 10 years.

Insufficient because this statement does not tell two things:-

a) No of houses remodeled last year

b) Age of the remodeled housesStatement -1 & 2 Combined---> 62 percent of the homes in City X are less than 10 years old & 32 percent of the homes in City X have been remodeled in the last 10 years

We know that 62% of houses age less than 10 years but we do not know what how many of 10 years old houses were remodeled last year.

Thus InsufficientSo the answer is E.Hope this detailed explanation will be helpful.
