Answer 1

Given :-

The difference between present ages of Ram and Gaurav is 10 years.

After 5 years, Ram's is twice of Gaurav's age.

⠀

To Find :-

Present age of Ram?

⠀━━━━━━━━━━━━━━━━━━━━━━━━

☯ Let's Consider the present age of Ram and Gaurav be x and y years respectively.

⠀

$\begin{gathered}\underline{\bigstar\:\boldsymbol{According\:to\:the\:question\::}}\\ \\\end{gathered}$

The difference between present ages of Ram and Gaurav is 10 years.

$\begin{gathered}:\implies\sf x - y = 10\\ \\\end{gathered}$

$\begin{gathered}:\implies\sf x = 10 + y\qquad\qquad\bigg\lgroup\bf eq\;(1) \bigg\rgroup\\ \\\end{gathered}$

After 5 years, Ram's is twice of Gaurav's age.

⠀

Their ages after 5 years,

⠀

• Age of Ram = (x + 5) years
• Age of Gaurav = (y + 5) years

⠀

Therefore,

⠀

$\begin{gathered}:\implies\sf (x + 5) = 2(y + 5)\\ \\\end{gathered}$

$</p><p>\begin{gathered}:\implies\sf x + 5 = 2y + 10\\ \\\end{gathered}$

$\begin{gathered}:\implies\sf (10 + y) + 5 = 2y + 10\\ \\\end{gathered}$

$\begin{gathered}:\implies\sf 15 + y = 2y + 10\\ \\\end{gathered}$

$\begin{gathered}:\implies\sf y - 2y = 10 - 15\\ \\\end{gathered}$

$\begin{gathered}:\implies\sf - y = - 5\\ \\\end{gathered}$

$</p><p>\begin{gathered}:\implies{\underline{\boxed{\sf{\purple{y = 5}}}}}\;\bigstar\\ \\\end{gathered}$

⠀━━━━━━━━━━━━━━━━━━━━━━━━

Now, Putting value of y in eq (1),

⠀

$\begin{gathered}:\implies\sf x = 10 + 5\\ \\\end{gathered} </p><p>$

$\begin{gathered}:\implies{\underline{\boxed{\sf{\pink{x = 15}}}}}\;\bigstar\\ \\\end{gathered}$

Therefore,

⠀

• Present age of Ram, x = 15 years
• Present age of Gaurav, y = 5 years
