Answer 2

Answer:

Profit percentage will be 11.419%.

Step-by-step explanation:

Given vendor buys bananas at 19 for Rs 18

So cost price of 1 banana is

$rupees \: \frac{18}{19}$

(By unitary method )

He sells that bananas at 18 for Rs 19

So, selling price of 1 banana is

$rupees \: \frac{19}{18}$

We know,

$cost \: price = 100\% \\ \frac{18}{19 } = 100\% \\ 1 = \frac{100}{ \frac{18}{19} } = 100 \times \frac{19}{18} \\ \frac{19}{18} = 100 \times \frac{19}{18} \times \frac{19}{18} = 111.419 \%$

[By unitary method ]

Profit percentage is (111.419-100)%=11.419%
