Question

Roy is now 4years older than erik and 2 years older than iris .if in 2years ,roy will be twice as old as erik,them in 2 years when would be roys age multiples

Answer 1

Let the present age of erik be "e".

Roy's present age = "e+4" years old.

Then, iris's age = "e+2" years old.

After 2 years Roy's age = "e+6" years old.

After 2 years Erik's age = "e+2" years old.

Acc to the question, e+6 = 2 * (e+2)

or, e+6 = 2e + 4

or, e = 2.

Therefore present age of Erik, Roy and Iris are 2, 6 and 4 years old respectively.

Therefore the product of Roy's and iris's age after 2 years would be 6*4 = 24.
