Step-by-step explanation:

Given -

A man got a 10°/. increase in his salary if his new salary is $121000$ .

To find -

The original salary

Solution -

To find the the original salary before the his new salary substract the 10% of  $121000$ from $121000$ .

$10$ % of $121000$ = $\frac{10}{100} \times 121000$

$10$ % of $121000$ = $10 \times 1210$

$10$ % of $121000$ = Rs. $12100$

The original salary = $121000 -$ $10$ % of $121000$

The original salary = $121000 - 12100$

The original salary = $108900$

∴ The original salary of man is Rs. 1,08,900 .

Answer 2

Answer:

Man's original salary was Rs. $110000$.

Step-by-step explanation:

Given : Percentage increase in salary = $10$%

         Man's new salary = Rs. $121000$

To find : Man's original salary = ?

Solution :

• It is given that the percentage increase in salary = $10$%

         Man's new salary = Rs. $121000$

• We have to find the man's original salary.
• Let, original salary be Rs. $x$.
• So, we have to calculate $10$% of $x$ plus $x$ which is equal to Man's new salary.
• The equation becomes,

             $10$% of $x$ + $x$ = $121000$

                  ∴  $\frac{10}{100} x+x=121000$

                 ∴  $\frac{10x+100x}{100}=121000$

                      ∴ $110x=121000*100$

                       ∴ $110x=12100000$

                         ∴ $x=\frac{12100000}{110}$

                           ∴ $x=110000$                                                    

• ∴  Man's original salary was Rs. $110000$.
