1) The profit earned by selling an article for Rs. 900 is double the loss incurred when the same article is sold for Rs. 450. At what price should the article be sold to make 25% profit ? A) Rs. 600 B) Rs. 750 C) Rs. 800 D) Data inadequate E) Rs. 850 Answer: Option BExplanation:Let C.P = Rs. $x$. Then, $900-x$ $=2(x-450)$ $\Rightarrow 3x=1800$ $\Rightarrow x = 600$ $\therefore$ Required S.P = 125% of Rs. 600 $=$ Rs. $\left(\frac{125}{100}\times 600\right)$ = Rs.750
