| A house-owner was having his house painted. He was advised that he would require 25 kg of paint. Allowing for 15% wastage and assuming that the paint is available in 2 kg cans. What would be the cost of paint purchased, if one can costs Rs. 16? |
A) Rs. 240
B) Rs. 180
C) Rs. 120
D) Rs. 360
Correct Answer: A
Solution :
| Total requirement of paint = 25 kg |
| Wastage =15% |
| Quantity of paint in each can = 2 kg |
| Now, 15%, gets wasted |
| \[\because \] \[2-\frac{15}{100}\times 2=2-0.3=1.7\,kg\]is used |
| \[\therefore \] Number of cans \[=\frac{25}{1.7}\approx 14.7\approx 15\] |
| \[\therefore \] Total price \[=15\times 16=Rs.\,\,240\] |
