Answer 2

✧ GIVEN :-

• Amit was given an increment of 20% on

his salary.

• New salary is Rs. 30600.

✧ To find :

• what was his salary before increment?

✧Solution :

$\bold \green {let \: \: his \: \: salary \: = \: X \: } \:$

$\bold \pink{given \: \: in crement \: \: = \: 20\%}$

$\bold{⇝ \:20 \: \% \: \: of \: x \: = \frac{20 \: x}{100} }$

$\bold{⇝ given \: \: new \: \: salary \: = \: 30600 \: }$

$\bold{⇝ x + \frac{20x}{100} \: = \: 30600 \: }$

$\bold{⇝ \frac{120x}{100} = \: 30600 \: }$

$\bold{⇝ 120 \: x \: \: = \:30,60,000 \: }$

$\bold{⇝ \: x \: \: = \: \: \frac{30,60,000}{120 \: } }$

$\bold \blue{⇝ \: x \: \: = \: \: 25,500. \: }$

$\bold \purple{Hence, \: \: his \: \: salary \: \: before \: \: increment \: was \: \: Rs \: 25,500 \: }$
