Question

Ram buys 40 pencils for Rs 70 and sells them at the rate of 30 pencils for Rs 80. Find gain or loss percent.

• A. 100
• B. 150
• C. 125
• D. 110

Answer 1

The correct option is A

100

Since CP of 40 pencils = Rs. 70
$\therefore$ CP of 1 pencil $=\frac{Rs.70}{Rs.40}=Rs.1.75$
Since SP of 30 pencils = Rs. 80
$\therefore$ SP of 1 pencil $=\frac{Rs.80}{Rs.30}=Rs.2.66$
$Gain=Rs.2.66-Rs.1.75=Rs.0.91Gain\%=\frac{Rs.0.91}{Rs.1.75}\times 100=52\%$
