Question

Roy is now 4 years older than erik and half of that amount older than iris. if in 2 years, roy will be twice as old as erik, then in 2 years what would be roys age multiplied by iriss age?

Answer 1

112

Let Roy's age be x..

Then, age of Erik = x-4

Age of Iris = 2x

AFTER TWO YEARS

Age of Roy = x+2 (eq 1)

Age of Erik = x-2. (eq 2)

Age of Iris = 2x + 2

From equations 1 & 2

x+2 = 2(x-2)

Therefore , x = 6

Age of Iris after two years = 14

Age of Roy multiplied by age of Iris after two years = 112
