Answer 1

Answer:

$\huge \bf \: Given$

In 5 years time, reshma will be three times old as she was 9 years ago.

$\huge \bf \: To \: find$

Present age

$\huge \bf \: Solution$

Let the present age be x

$\sf \mapsto \: (x + 5) = 3(x - 9)$

$\sf \mapsto \: x + 5 = 3x - 27$

$\sf \mapsto \: 3x - x = 27 + 5$

$\sf \mapsto \: 2x = 32$

$\sf \mapsto \: x \: = 32 \div 2$

${\mathfrak {\color {emerald} {\fbox{x \: = 16}}}}$

Reshma is 16 years old now.
