Question

The salary of a person was increased by 15%.if his salary now is ruppe 9936,what was initial salary<br />​

Answer 1

New salary after increase = Rs. 9936

Let x be the Initial salary

Initial salary + 15% of initial salary = New Salary

x+15%(x)=9936x+(15/100)(x)=9936

x+(3/20)(x)=9936

x+3x/20=9936

(20x+3x)/20=9936

23x=9936*20

23x=198720

x=198720/23

x=8640

Rs. 8640 was his initial salary.

hope it's helpful.

Answer 2

$\huge\purple{\fbox{\fbox{\red{\mathcal{Bonjour}}}}}$

let the initial salary be X

$x + 15\% \: of \: x = 9936$

$= > \frac{x}{1} \times \frac{100}{100} + \frac{15}{100} \times x = 9936$

$= > \frac{100x + 15x}{100} = 9936$

$= > \frac{115x}{100} = 9936$

$= > x = 9936 \times \frac{100}{115}$

$= > x = 9936 \times \frac{20}{23}$

$= > x = 432 \times 20$

$= > x = 8640(ans)$
