Question

Nancy is 5 years younger than her brother Stan. Last year she was twice as young as he was. How old is each of them now?

Answer 1

Nancy: 5 Stan: 10

5 is 5 years
younger then Stan
And 5 is twice as
young as 10

Answer 2

Answer:

Nancy is 6 years old and Stan is 11 years old now.

Step-by-step explanation:

Let the present age of Stan be x.

Then age of Nancy = y

x - y = 5

Last year she was twice as young as he was

Age of Nancy last year = y-1

Age of Stan last year = x-1

2 × (y-1)= x-1

2y -2 = 5 + y -1

y = 6

x = y + 5 = 6 + 5 = 11

Nancy is 6 years old and Stan is 11 years old now.
