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 coat of paint purchased if one can costs Rs. $16$?

• A. Rs. $240$
• B. Rs. $360$
• C. Rs. $180$
• D. Rs. $120$

Answer 1

Answer: (A)

The correct option is A Rs. $240$
$25$ kg of paint with $15\%$ waste would amount to:

$\Rightarrow 25\times \left(1.15\right)=28.75$ kgs of paint

The paint is available in $2$ kgs cans, so $14$ cans will take care of the $28$ kgs and $1$ more can for the $0.75$ kgs, totalling $15$ cans.

$\Rightarrow 15\times 16=240$

The cost of paint purchased is Rs. $240$.
