Question

a is 5 yrs older than b 5 yrs ago a wastwice as old as b find present age

Answer 1

Here is the answer to your question.

 

Let the present age of A be x

Present age of B = 5 + x

A is age five years ago = x – 5

B age five years ago = 5 + x – 5 = x

According to question,

x = 2(x – 5)

x = 2x – 10

–2x + x = –10

–x = –10

x = 10

 

A is present age = 10 years

B is present age = 10 + 5 = 15 years
