1.	If 6 articles are sold for Re 1 then there is a loss of 20%. In order to gain 20%, what must be the number of articles sold for Re 1 ?
Answer» S.P. of 6 articles = Re 1, Loss = 20 % \(\therefore\) C.P. of 6 articles = \(\frac{1\times100}{(100-20)}\)= \(\frac{100}{80}\) = \(\frac{5}{4}\) = 1.25 If the gain is 20%, then S.P. of 6 articles = \(\frac{1.25\times120}{100}\) = Rs 1.50 \(\therefore\) For Re 1, 4 articles are sold.

Answer»

S.P. of 6 articles = Re 1, Loss = 20 %

\(\therefore\) C.P. of 6 articles = \(\frac{1\times100}{(100-20)}\)= \(\frac{100}{80}\) = \(\frac{5}{4}\) = 1.25

If the gain is 20%, then S.P. of 6 articles = \(\frac{1.25\times120}{100}\) = Rs 1.50

\(\therefore\) For Re 1, 4 articles are sold.
