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 \: (60)/(200)`

`\qquad \tt \dashrightarrow \:0.3 \: \: kobo`

Now, Cost price for 8 oranges :

`\qquad \tt \dashrightarrow \:0.3 * 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 \: (9.6)/(2.4) * 100`

`\qquad \tt \dashrightarrow \:4 * 100`

`\qquad \tt \dashrightarrow \:400 \: \%`
