A simple maths problem...

Post by just a Frenchie »

Alf says to Bill :
" I’m twice the age you had when I had the age you have and when you'll be my age, the sum of our ages will be 81. What age am I ?"
(let’s say that Alf’s age is A and Bill’s age is B)

:lol: :lol: :lol:

A is 36
B is 27

There is nine years difference. So nine years ago...

A was 27
B was 18... So A today is twice Bill's age nine years ago (18 x 2 = 36).

Seems to work out :roll: but having got the last one wrong, I'm not too sure.

That’s what I made it as well. The pattern of numbers I used was 36 27 18

A is 36, B is 27. In 9 years A will be 45 and B will be 36. 45+36=81
