At a local appliance manufacturing facility, the workers

BTGmoderatorLU wrote:At a local appliance manufacturing facility, the workers received a 20% hourly pay raise due to extraordinary performance. If one worker decided to reduce the number of hours that he worked so that his overall pay would remain unchanged, by approximately what percent would he reduce the number of hours that he worked?

A. 83%
B. 80%
C. 20%
D. 17%
E. 12%

The OA is D.

Let us assume, Hourly Rate=$100
No of hours worked=6
Salary earned=$600
Now, the worker wants to keep the pay unchanged at $600
New Hourly Rate=120% of $100=$120
New no of hours worked=$600/$120=5 hours
Required %=6-5/6=1/6=16.66%=17%
Answer D.

Has anyone another approach to solve this PS question? Regards!
