Question

Ram buys 40 pencils for ₹ 70 and sells them at the rate of 30 pencils for ₹ 80. Find his gain percent.

• A. 52 %
• B. 25 %
• C. 62 %
• D. 84 %

Answer 1

The correct option is A 52 %

Given, the cost price of 40 pencils $=₹70$
Therefore, the cost price of 1 pencil
$=\frac{₹70}{40}$
$=₹1.75$.
Given, the selling price of 30 pencils $=₹80$
Therefore, the selling price of 1 pencil
$=\frac{₹80}{30}$
$=₹2.66$.

$Gain=Sellingprice-Costprice$
Hence,
$Gain=2.66-1.75=0.91$.

$Gainpercent=\frac{Gain}{Costprice}\times 100$

$=\frac{0.91}{1.75}\times 100$

$=52$%.
