Answer 2

In context to the question it is asked to find the total value of age two quantities are given as follows

1) 35 years 11 months

2) 11 years 7 months

so by simple addition we get the answer

for years

$35+11\\=46 years$

now for months

$7+11\\=18 months$

now by converting this months to year we get

12 months =1 year

hence

$18 months=1.6 years$

so the total is

$46+1.6\\=47.6 years$
