Answer:The present age of both of them are Christopher = 42 years, and Ishaan = 84 years.
Step-by-step explanation: Solution:
Let present age of:
Christopher =
x
yrs
Ishaan =
2
x
yrs ( given that Ishaan is 2 times as old as Christopher)
35 yrs ago:
Age of Christopher = (
x
- 35)yrs
Age of Ishaan = (
2
x
- 35) yrs
According to question, 35 yrs back, Ishaan was 7 times older than Christopher.
Therefore
7 X (
x
- 35) = (
2
x
- 35)
7
x
- 245 =
2
x
- 35
7
x
-
2
x
= 245 - 35
5
x
= 210
x
= 42
So present age of Christopher =
x
= 42 yrs
&
Present age of Ishaan =
2
x
= 84 yrs
Check your solution:
As 84 is 2 times of 42 so Ishaan is 2 times older than Christopher.
35 yrs ago, Christopher was (42 - 35) = 7 yrs old and Ishaan was (84 - 35) = 49 yrs old so Ishaan was 7 times older than Christopher then.
