Answer 1

$\huge \fbox \green{❤Answer:}$

$\sf \colorbox{pink} {Let's Kailash Salary =100}$

$⇒Old \: Expenses = \frac{85}{100} \times 100 = 85$

$⇒New \: Salary \: 136\% \: of \: 100 = Rs.136$

$⇒New \: Expenses \: 140\% \times 85$

$= \frac{140}{100} \times 85 = Rs.116$

$Save = Rs.136 - Rs.119 = Rs17$

$\sf \colorbox{skyblue} {Preventing Saving}$

$= \frac{17}{136} \times 100 = 12.5\%$
