Question

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

Answer 1

(a) Rs 240

Paint required = 25 kg + 15% of 25 kg 

= 25 kg + 0.15 × 25 kg = 28.75 kg

\(\therefore\) Number of 2 kg cans of paint required = 15

Cost of paint purchased = 15 × Rs 16 = Rs 240
