Question

Ben is 39 years old and Ishaan is 3 years old. How many years will it take until Ben is only 4 times as old as Ishaan?

Answer 1

Solutions :-

Given :
Ben's age = 39 years
Ishaan's age = 3 years

Let the x years will it take until Ben is only 4 times as old as Ishaan.


According to the question,

=> 39 + x = 4 (3 + x)
=> 39 + x = 12 + 4x
=> x - 4x = 12 - 39
=> - 3x = - 27
=> x = - 27/ - 3 = 9


Hence,
After 9 years, the age of Ben will be 4 times as old as Ishaan.

Answer 2

$\underline{\underline{\Huge\mathfrak{Answer ;}}}$

Stated that ;-
• Ben's Age => 39 years.
• Ishaan's Age => 3 years.

Assuming the value as $<b>"Y"</b>$ years that will take until Ben is only 4 times as old as Ishaan.

Now ,
According to the Problem ;

$= > 39 + y = 4(3 + y)$
$= > 39 + y = 12 + 4y$
$= > y - 4y = 12 - 39$
$= > - 3y = - 27$
$= > y = \frac{ - 27}{ - 3} = 9$

Therefore ,
After $<b>9</b>$ years , Ben's age will be 4 times as much old as Ishaan's.
