Answer 1

Question :-

• In 5 years time reshma will be three times old as she was 9 years ago ,how old is she now?

Required Solution :-

• Reshma is 16 years now.

Explanation :-

• Let the present age of Reshma be X years.

Provided That :-

• Her age after 5 years = X+5
• Her age 9 years ago = x-9

$\qquad$ According to the question :-

$\qquad \pmb{\sf\longrightarrow X+5 = 3(x-9)}$

$\qquad \pmb{\sf\longrightarrow X+5= 3x- 27}$

$\qquad \pmb{\sf\longrightarrow X-3x = -27-5}$

$\qquad \pmb{\sf\longrightarrow -2x= -32}$

$\qquad \pmb{\sf\longrightarrow 2x= 32}$

$\qquad \pmb{\sf\longrightarrow X= \cancel{\dfrac{32}{2}}= 16}$

$\qquad \longrightarrow {\pink{\underline{\underline{\pmb{\sf{ X = 16 }}}}}}$

Therefore–

• Reshma is 16 years now.
