john is 3 years older than peter. ten years ago the sum of their ages was 59. in years, how old is john now?

John's age + peter's age = 59 (ten years ago)

p represents peter's age in this equation

(p + 3) + p = 59

2p + 3 = 59

2p = 56

p = 28

peter was 28, so john was 31.

(28 + 3 = 31)

that was 10 year's ago, so now we find how old john is today.

31 + 10 = 41

john is 41.

I think he is 62
