Greg and Martin's age when added together come to a total of 60 years. Now Greg is twice as old as Martin was when Greg was half as old as Martin will be when Martin is five times as old as Greg was when Greg was five times as old as Martin. With all this excellent data how old is Greg?

Answer 1

Let G be the age of Greg Let M be the age of Martin

Greg and Martin's age when added together added together come to a total of 60 years.

So,
G+ M = 60
Greg is twice as old as Martin
G = 2M
G+ M = 60
2M + M = 60
3M = 60
M = 20
G = 2 * 20 = 40
Greg was 40 years old
