rasaki is five times older than his son. five years ago the sum of rasaki and his sons age was 62.How old are they now?

The mother is 60 years old and the son is 12 years old.

5 years ago their age sum was 62.

Now after 5 years their age sum is 72(62+5(mothers) + 5(Sons)

so now if the mother is 5 times the age of the son then,

their age ratio is 1x:5x . so to find their age = 1+5=6

so 72/6 = 12 .

so the son is 12 years old (1x).

and the mother is 12 × 5 = 60 (5x).

and when you add it is 60 + 12 =72 .

I hope it will help you...
