Question

A man sold two paintings at $Rs924$ 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

S.P = 924

Gain % = 20

Loss % = 20

$C.P=\frac{100}{100+20}\times 924=\frac{100}{120}\times 924=770$

C.P with 20% Loss = $\frac{100}{100-20}\times 924=\frac{100}{80}\times 924=1155$

with CP of one article = 770

C.P of 2nd article = 1155

total CP = 770+1155= 1925

total S.P = $924\times 2=1848$

total loss = $1925-1848$

= 77 Rs
