If the actual cost exceeds the estimated cost of the company, then the additional cost is cut down by decreasing the cost of bricks. By what percentage of cost on bricks is reduced in 2011 if the actual cost of the company in that year was Rs.486 lakhs?
Options:
A) 9.25 
B) 11.33
C) 12 
D) 16.67
E) 15
Solution:
Actual cost in 2011 = Rs.486 lakhs

Estimated cost in 2011 = 468

so, difference = 18

Number of bricks in 2011 = 150

Hence, Required % = 18 is what % of 150 = 12
