Answer 2

Note : In a dozen there are 12 banana

Given : Cost price of banana per dozen = 10 rupee

Selling price of banana per piece = 1 rupee

To find : Gain or loss percentage

Solution

Selling price of per dozen =

$\: 1 \times 12 = 12 \: rupee$

Now we find that selling price is greater than cost price

Therefore, their is profit

Profit = selling price - cost price

=> p = 12 - 10

=> p = 2

Now we can find the profit percentage by putting it in the formula

$profit \% = \dfrac{profit}{cost \: prize} \times 100$

$p\% \: = \dfrac{ \cancel{2}}{ \cancel{10}} \times \cancel{100}$

$\large{\bold ={\boxed {20\%} }} \: \:$
