Ishaan is 2 times as old as Christopher. 35 years ago, Ishaan was 7 times as old as Christopher. How old is Ishaan now?

Answer 1

I = 2c

i-35 = 7(c-35)

2c - 35 = 7(c-35)

2c - 35 = 7c - 245

-35 = 5c - 245

210 = 5c

c = 42

Ishann is 84

Christopher is 42

35 years ago, Ishann was 49 and Christopher was 7, which is 7 times as old

Ishann is 84

Christopher is 42
