Question 1144261: Mary is 9 years younger than Anne. Tom is twice as old as Anne. If the sum of their ages is 95, how old are Mary, Tom, and Anne? Answer by ikleyn(52788) (Show Source):
Let x be the Anne's age.
Then the Mary's age is (x-9) years and Tom's age is 2x years.
The total is
x + (x-9) + 2x = 95.
Simplify and solve for x.
4x - 9 = 95,
4x = 95 + 9
4x = 104
x = 104/4 = 26.
ANSWER. Anne is 26 years old; Mary is 26-9 = 17 years old; Tom is 26*2 = 52 years old.
CHECK. 26 + 17 + 52 = 95 years. ! Correct !
