Question

The ages of 3 sisters are Consecutive Integers. The sum of their ages is 45. Calculate Their Ages.

Answer 1

The three sisters are 14, 15 and 16

Answer 2

45=(x)+(x+1)+(x+2)
45=x+x+1+x+2
45=3x+3
42=3x
Divide both sides by 3:
14=x
The youngest one is 14, then 15, then 16.

Hope this helps :)
