Question 365685: the ages of john and mary is 27 years. Mary's age plus twice john's age is 40. How old is each person? Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! j+m = 27, this means m = 27-j.
also it is given that m+2j = 40.
Hence 27-j+2j = 40 or j = 13, and m = 14. Therefore john is 13 yrs old, and mary is 14 yrs old.
