loses 15% on the other. Does he gain or loss on the whole and by how much
percent?​

Answer 1

Answer:

one chair=15percent

so,two chairs=30percent

if he loses 15 percent

he gain rs 470 and lose nothing

Answer 2

He would have 2.25% loss on the whole.

Loss % on one chair = 15%

Profit % on other chair = 15%

So, In whole, there will be loss%

say x = 15%

So, Loss% would be

$\dfrac{x^2}{100}\\\\=\dfrac{15^2}{100}\\\\=\dfrac{225}{100}\\\\=2.25\%$

Hence, he would have 2.25% loss on the whole.
