Question

Ishaan is 727272 years old and William is 444 years old. How many years will it take until Ishaan is only 555 times as old as William?

Answer 1

Answer:

It will take 13 years to Ishaan age will be 5 times William age.

Step-by-step explanation:

Given : Ishaan is 72 years old and William is 4 years old.

To find : How many years will it take until Ishaan is only 5 times as old as William?

Solution :

Let x be years since today.

According to question,

Ishaan's age is I=72+x

William's age is W=4+x

Now, We want the time for Ishaan age will be 5 times William's age:

i.e. $I=5W$

$72+x=5(4+x)$

$72+x=20+5x$

$72-20=5x-x$

$52=4x$

$x=13$

It will take 13 years to Ishaan age will be 5 times William age.

By this time William will be 17 years old and Ishaan will be 85 years old.
