Explanation:

Let the number of employees in beginning is 3a and now is 2a
Let the wage per employee initially be 20b and now 27b
Total wages = no. of employees x wage per employee.
= 3a x 20b
= 60ab
Now,
= 2a x 27b
= 54ab
Profit %ge = ( 60 – 54 ) / 60 x 100 = 10%

Hence, option 3 is the correct answer.
