Question

Answer 1

Friends, we know we will need gain amount to get gain percent, right. So lets get gain first.

Let the cost price of 1 pen is Re 1

Cost of 8 pens = Rs 8

Selling price of 8 pens = 12

Gain = 12 - 8 = 4

\begin{aligned}

Gain\% = \left( \frac{Gain}{Cost} * 100 \right)\% \\

= \left( \frac{4}{8} * 100 \right)\% = 50\%

\end{aligned}

Answer 2

The gain percent is 50%

Step-by-step explanation:

Let the cost price of 1 book be Re.1

Cost price of 8 books = Rs.8

Cost price of 12 books = Rs.12

cost price of 12 books is equal to the selling price of 8 books

Sp of 8 books = CP of 12 books = Rs.12

CP of 8 books = Rs.8

SP>CP

So, Profit

$Profit\% = \frac{SP-CP}{CP} \times 100 \\Profit\% = \frac{12-8}{8} \times 100 \\Profit\% =50\%$

Hence the gain percent is 50%
