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 ?
A
5%
B
10%
C
20%
D
25%
Correct Answer: 10%
Even if the percentage of his commission remains the same, his total commission will increase due to the increament of his salary. Previous commission = 10% of 5000 = 500 New salary = 5000 + 10% of 5000 = 5000 + 500 = 5500 New commission = 10% of 5500 = 550 Increament of commission = (550 - 500) / 500 x 100% = 10%
