Answer 2

Answer : $\bold{Selling \: Price \: of \: 1 \: banana \: = \: Rs \: 3}$



Explanation -


Given :

Cost Price of dozen bananas = Rs 20

Profit % = 80 %


Finding the Profit -

Profit on Cost Price.


$20 \times \dfrac{80}{100} = 16$

Profit = Rs 16



Finding the Selling Price of dozen bananas -

Selling Price = Cost Price + Profit

Selling Price = 20 + 16

Selling Price = 36.


So, Selling Price of dozen bananas = Rs 36.




Finding the Selling Price of 1 banana -

1 dozen = 12 bananas .


12 bananas = Rs 36

1 banana = 36/12 = 3.


So, Selling Price of 1 banana = Rs 3.
