Let x represent Your age
%2835%2A4+-+x%29%2F3+=+40
140 - x = 120
20 = x, your age

If the average age of four people is 35
then the total of the ages is 4 x 35 = 140.
If the average age of the same group, less
you is 40, then the total of the three people
is 120.
140 - 120 = 20
Your age is 20.
Hope this helps.
