onginal salary​

Answer 1

GIVEN :-

• Salary of Aman increased by 10 %.
• New Salary of Aman is 7154000.

TO FIND :-

• The original salary of Aman.

SOLUTION :-

Let the original salary of Aman be "x".

✮ Accoding to Question,

➳ x + 10% of x = 7154000

➳ x + 10/100 × x = 7154000

➳ x + 10x/100 = 7154000

➳ (100x + 10x)/100 = 7154000

➳ 110x/100 = 7154000

➳ 110x = 7154000 × 100

➳ 110x = 715400000

➳ x = 715500000/110

➳ x = 6503636.36

Hence original salary of the Aman was 6503636.36.

Answer 2

Given :

• Aman got a 10% increase in his salary. If his new salary is 71.54.000.

　

To find :

• What is his orginal salary.

　

According to the question :

• Let us assume "x" as Aman's orginal salary.

　

Calculations :

$:\implies\sf{71,54,000 = \dfrac{10}{100} \times x}$

　

$:\implies\sf{71,54,000 = \dfrac{11}{10x}}$

　

$:\implies\sf{x = 71,54,000 \times \dfrac{10}{11}}$

　

$:\implies\sf{x = \dfrac{71,540,000}{11}}$

　

$:\implies{\bold{\underline{\boxed{\bold{x = 6,503,636.36}}}}}$

　

Therefore, 6,503,636.36 is his orginal salary.
