Question

A man sold two horses for Rs.1200 each getting 20% profit on one and 20% loss on the other.Find the overall gain or loss %.​

Answer 1

Step-by-step explanation:

In the case where loss and gain percentage is common on same selling price, always a loss incurs in total deal. And this can be calculated by a short-cut:

Loss on total deal

$= > ( \frac{common \: loss \: or \: gain \: percentage}{10} ) {}^{2}$

$= > ( \frac{20}{10} ) {}^{2}$

$= > 4 \: percent$

Alternatively, It can be also calculated through Graphic Change Method: This can be given by,

100 == 20% gain ⇒ 120 == 20% loss ⇒ 96

Loss = 4% (As 100 became 96)
