A vendor buys oranges at 86 per dozen and sells them at 15 for 43. Find his loss per cent

1. First we need to find cost price (cp) of 1 item

2. Secondly, we need to find selling price(sp) of 1 item

3.loss= cp - sp

4. loss% = loss/cp *100

Completly solved :

Cp of 12 items is ...₹ 86

Cp of one item is 86/12 = ₹ 7.17

Sp of 15 items is ₹ 43

Sp of 1 items is ₹ 43/15= ₹ 2.87

Loss = 7.17 - 2.87 = ₹4.3

Loss% =4.3/7.17 *100 = 59.97%

for the points! : )
