Question

A man sold two painting in rupees 924 each. on one he gains 20% and on the other he loses 20%.How much does he gain or lose in the whole transaction?

Answer 1

Answer:

$Total \:loss =Rs\:77$

Step-by-step explanation:

$i) Selling \:price \: of \: a\\painting (s.p) = Rs 924\\gain(g)=20\%$

$cost\:price (c.p) = \frac{s.p\times 100}{100+g}\\=\frac{924\times 100}{100+20}\\=\frac{924\times 100}{120}\\=Rs\:770$

$ii) Selling \:price \: of \: a\\painting (s.p) = Rs \:924\\Loss(l)=20\%$

$cost\:price (c.p) = \frac{s.p\times 100}{100-l}\\=\frac{924\times 100}{100-20}\\=\frac{924\times 100}{80}\\=Rs\:1155$

$Now,\\Total \:cost\:price(TCP)\\= Rs\:770+Rs\:1155 = Rs\:1925\\Total\: selling \:price (TSP)\\= Rs\:924+Rs\:924 = Rs\:1848$

(TCP) > (TSP)

He gets loss.

$Total \:loss = Rs\:1925-Rs\:1848\\=Rs\:77$
