• question_answer 40) By selling an article for Rs.1000, a man loses 30%. At what price should he sell it in order to gain 20%? A) $Rs.\,\,1200$                            B) $Rs.\,\,2000$C) $Rs.\,\,1714\frac{3}{7}$    D) $Rs.\,\,1822\frac{4}{7}$

(c) Let loss in % age be ${{x}_{1}}$ and gain in % age be ${{x}_{2}}\Rightarrow {{x}_{1}}=30,\,{{x}_{2}}=20$ We have, $\frac{S.{{P}_{1}}}{100-{{x}_{1}}}=\frac{S.{{P}_{2}}}{100+{{x}_{2}}}$ $S.{{P}_{2}}=Rs.1000\times \frac{120}{70}=Rs.\,\frac{1200}{7}=1714\frac{2}{7}$
