Answer 1

Answer:

Given :

$\sf{Salary\:increased = 10\%}$

$\sf{New \:salary \:of\:the\:man= 1,54,000}$

To find :

$\textsf{The\:original \:salary\:of\:the\:man}$

Taken :

To find the original salary of the man use this formula -:

$\sf\boxed{O=\dfrac{100\%-I}{100\%}\times\:N}$

Where,

O = Original salary of the man

I = Salary increased

N = New salary of the man

Concept :

We have subtracted 100% with 10% because his salary is increased and it became 100% as 1,54,000 . So , we have subtracted to find the original salary of the man .

Solution :

$\sf:\implies{O=\dfrac{100\%-10\%}{100\%}\times1,54,000}$

$\sf:\implies{O=\dfrac{90\%}{\cancel{100\%}}\times\cancel{1,54,000}}$

$\sf:\implies{O=90\times1,540}$

$\sf:\implies{O=1,38,600}$

So , the original salary is ₹1,38,600 .

Answer :

Original salary of the man before the salary increased by 10 % is ₹ 1,38,600 .
