3 years ago Paul was 5 and his mother was 5 times his age.(1) How old will his mother be in 4 years` time? (2) How old will Paul be in 4 years` time?
If 3 years ago Paul was 5 yrs old, now he is 5 + 3 = 8 yrs old
If his mother was 5 times his age she was 5 ∙ 5 = 25 yrs old, now she is 25 + 3 = 28 yrs old
After 4 years mother will be 28 + 4 = 32 yrs old
After 4 years Paul will be 8 + 4 = 12 yrs old
