Answer:
20% ans.
Step-by-step explanation:
Total Income = Hourly Wage * No of hours
If we want to keep the total income same,
Hourly Wage * No of hours = New Hourly Wage * New No of hours
Hourly Wage * No of hours = 5/4 * Hourly Wage * New No of hours
So New No of hours/No of hours = 4/5
A decrease of 1/5 i.e. 20%
hope this helps you, take care
