Question

Neeta sold two articles at Rs840 each. On one she gains 20% and on other she loses 20%. How much does she gain or loss in the whole transaction. also find her loss or gain percent in whole transaction.​

Answer 1

Answer:

sp of two articles=2×840=₹ 1680.

on 1st article she gains 20%

therefore, CP of 1st article=100/(100+gain%)×840

$= \frac{100}{120} ×840$

=100×7

=700.

➠while on 2nd article, she losses 20%

therefore, CP of 2nd article =100/(100-loss%)×840

$= \frac{100}{80} \times 840$

=1050.

➠Therefore total CP of two articles

=700+1050

=1750

since, CP>SP

Loss=1750-1680

=70

Therefore, loss%=loss/CP ×100

=70/1680×100

=41.66%.
