Pie Chart Questions If it is given that power constitutes 50% of the other costs and the power cost declines by 10%, then by what percentage will the total expenses of the company decrease?
(a) 2.5%
(b) 5%
(c) 10%
(d) Cannot be determined.

Explanation:

Assume that the total expense of the company = Rs. 100.
Then, Other costs = Rs. 50

Now, Power cost = 50% of the other costs = 50% of 50 = Rs. 25.
Decrease in power cost = 10% of original rate = 10% of 25 = Rs. 2.5.

Hence, the percentage decrease in expenses = (2.5/100) × 100 = 2.5%.
