Question 1004552: The sum of the ages of two sisters Anna and Linda is 60years.if Anna is three times as old as Linda, calculate Linda's age Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call their ages A and L.
From the facts we have
A + L = 60 and
A = 3L
Substitute the second into the first and get
3L + L = 60
4L = 60
L = 15 and then
A = 45
