The payment per hour for a daily-wages employee is increased by 33.33 and the working time is reduced by 33.33%. What is the percentage change in the employee's income ?

A 11.11% decrease

B 21.11% increase

C 11.11% increase

D 21.11% decrease

Correct Answer: Option A

If earlier he is getting Rs. 1 per hr and working for 1 hr, income = Rs. 1
Now he is getting Rs 1.3333 per hr and working for 0.66667 hrs

Then income for 0.66667 hrs = Rs. 0.8889.

If payment per hr is increased by 33.33 % and working hours dereased by 33.33%, then 11.11 % decrease in income.
