Ishaan is 2 times as old as Christopher. 35 years ago, ishaan was 7 times as old as Christopher
Natalija [7]

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.
