Correct Question:

A person salary increases from Rs. 7200 to Rs. 8100. What is the the percentage increase in his salary?

Given:

• Orignal Salary = Rs. 7200
• Increased Salary = Rs. 8100
• How much increased = Rs. 8100 - Rs. 7200 = Rs. 900

What To Find:

Find the increased percentage.

Solution:

Using the formula,

⇒ $\sf{Increased\:\% = \dfrac{Increased\:in\:salary}{Oringinal\:salary} \times 100}$

Substitute the values,

⇒ $\sf{Increased\:\% = \dfrac{900}{7200} \times 100}$

Cancel the zeros in 900 and 7200,

⇒ $\sf{Increased\:\% = \dfrac{9}{72} \times 100}$

Cancel 9 and 72,

⇒ $\sf{Increased\:\% = \dfrac{1}{8} \times 100}$

Cancel 100 and 8,

⇒ $\sf{Increased\:\% = 12.5\:\%}$

∴ Therefore the increased percentage is 12.5 %.
