Mr. Khan's salary is Tk. 5000.00 and he gets 10% commission of his salary. If his salary increased by 10%, by what percent his commission will increase?
Increase in salary = 10% of 5000 = (10/100) × 5000= 500
Therefore, Mr. Khan's new salary after the 10% increase will be:
New salary=5000+500 =5500
His commission is 10% of his salary, so initially, his commission was:
Commission = 10% of 5000 = (10/100) ×5000= 500
After the increase in his salary, his commission will be:
New commission = 10% of 5500 = (10/100) ×5500 = 550
To calculate the percentage increase in his commission, we can use the following formula:
Percentage increase = {(New commission - Initial commission) / Initial commission} ×100
Let's substitute the values:
Percentage increase = {(550 - 500) / 500}×100= (50 / 500) × 100= 0.1 × 100 = 10%
Therefore, the commission will increase by 10% when Mr. Khan's salary increases by 10%
