Answer 1

$\huge{Hey\:Mate\:Here\:Is \:Your\:Answer}$

$\textbf{Given That....}$

Sushil Is Now 4 Times As Old As Sunil And 5 Years Ago Sushil Was 7 Times As Old As Sunil And We Need To

Find Their Present Ages.

So Now Let's Move For Solution....

$\textbf{Solution...}$

So To Find The Present Ages Of Sushil and Sunil Follow The Simple Steps

$\underline\bold{Step\:1 \:- \:Divine \:All \:Required\: Values\: With\: The \:Help\:of\:Variables}$

Now Let ...

The Present Age Of Sunil Be = X

So According To Question Sushil Is Now 4 times The Age Of Sunil Therefore

Present age Of Sushil = 4x

Now Thier Ages Before 5 Years Are ....

Age Of Sunil 5 Year Ago = X - 5

So

Age Of Sushil Before 5 years = 4x - 5

$\underline\bold{Step\: -\:2\: Form \:An\: Equation\: With\: Given\: Information...}$

That Is ...

According To Question It's Said That Sushil Was 7 Times Older Than Sunil before 5 years ...

Therefore

Sushil's Old Age = 7 Times Of Sunil's Onld Age ...

So Now Putting Past Ages Of Sushil And Sunil Here .. we have ....

$4x - 5 = 7(x - 5)$

$\underline\bold{Step \:- \:3 \:\:Solve\:The\:Formed\:Equation}$

That Is ....

$4x - 5 = 7(x - 5)$

Now Open Bracket And Find The Product.(LHS)

That Is ...

$4x - 5 = 7x - 35$

Now Taking All Variable Terms To LHS and constant To RHS We Have ...

$- 5 + 35 \: = 7x - 4x$

Now Solving Both Side We Have ....

$30 = 3x$

Taking 3 To LHS We Have ...

$30 \div 3 = x$

Therefore We Have ....

$\boxed{x \:= \:10}$

$\underline\bold{Step\:-\:4\:Put\:The\:Value\:Of\:X\:In\: Present\:Ages\:Of\:Both}$

So We Have...

$\textbf{Present Age Of Sunil = X = 10 years }$

And

$\textbf{Present Age Of Sushil = 4x = 4\times10 = 40 years}$

Therefore Required Answer Is...

$\boxed{Sunil\:=\:10\:Years \:And\:Sushil\:=\:40\:years}$

$\blue{Be\: Brainly...}$
