Five years ago, peter was three times as old as alex. if at the present time alex is ten years old, how old will peter be in the next three years?
From the question, were have the present age of alex as: 10 years.
five years ago, Alex was (10-5)years
we are told that peter was 3 times as old as alex. so, the age of peter, five years ago was (5*3) = 15 years
the current age of peter is: 15+5 = 20years.
in the next three years, the age of Peter will be: 20+3
= 23years
in the next three years, Peter will be 23 years
