Question

a dealer sells two office tables for rupees 3000 each .he gains 20 percent on one table and loss 20% on other.what percent does he gain or loss on the whole transaction

Answer 1

Sold price of tab 1 =3000

Gain is
$\frac{20}{100} 3000 = 600$
sold price of tab 2=3000

Loss is
$\frac{20}{100} 3000 = 600$
he earned 600 gain in tab 1 and he lost 600 in tab 2

So no gain or no losss
