In an office the number of employees reduces in the ratio of 3 : 2 and the wages increases in the ratio of 20 : 27, What is the profit percentage of employees over the previous wages?
-
- 10%
- 9.09%
- 11.11%
- none of these
Correct Option: A
Let the number of employees in beginning = 3a
Let the wage per employee = 20b
Total wages = no. of employees x wage per employee.
= 3a x 20b
= 60ab
Let the number of employees in the end= 2a
Let the wage per employee = 27b
Total wages = no. of employees x wage per employee.
= 2a x 27b
= 54ab
Profit (%) = [ ( 60 - 54 ) / 60 ] x 100 = 10%
