Problema Solution
Victoria father is 5 times older than Victoria and Victoria is twice as old as her sister Mariela. In two years, the sum of their ages will be 58. How old is Victoria now?
Answer provided by our tutors
Let x = Victoria's age.
Then father's age is 5x.
Sister's age is x/2.
In two years, the sum of their ages will be 58:
(x+2) + (5x+2) + (x/2+2) = 58
Multiply by 2:
2x+4 + 10x+4 + x+4 = 116
13x + 12 = 116
13x = 104
x=8
Ans: 8
