Question

Cp of 4 bananas =1
Sp of 3 bananas =1
Profit or loss percentage

Answer 1

$\huge\red{Hi\: Friend}$

CP of 4 bananas is 1
CP of 1 bananas is 1/4

SP of 3 bananas = 1
SP of 1 bananas = 1/3

As SP is more than CP so there is profit

Profit = SP - CP
$= \frac{1}{3} - \frac{1}{4} \\ = \frac{4 - 3}{12} \\ = \frac{1}{12}$
Now
Profit % = Profit× 100/CP
$= \frac{ \frac{1}{12} }{ \frac{1}{4} } \times 100 \\ = \frac{1}{12} \times \frac{4}{1} \times 100 \\ = 33.33\%$

Profit% = 33.33%
