Question

A trader buys 200 oranges for 60 kobo and sells them at 8 for 12 kobo.what is his gain​

Answer 1

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve ~

Cost price for each Orange :

$\qquad \tt \dashrightarrow \: \dfrac{60}{200}$

$\qquad \tt \dashrightarrow \:0.3 \: \: kobo$

Now, Cost price for 8 oranges :

$\qquad \tt \dashrightarrow \:0.3 \times 8$

$\qquad \tt \dashrightarrow \:2.4 \: \: kobo$

And we have been given that selling price for 8 oranges is 12 kobo.

Therefore, the gain is :

$\qquad \tt \dashrightarrow \:12 - 2.4$

$\qquad \tt \dashrightarrow \:9.6 \: \: kobo$

Percentage gain is ~

$\qquad \tt \dashrightarrow \: \dfrac{9.6}{2.4} \times 100$

$\qquad \tt \dashrightarrow \:4 \times 100$

$\qquad \tt \dashrightarrow \:400 \: \%$
