Question:
Tick (✓) the correct answer:
The profit earned on selling an article for Rs 625 is the same as loss on selling it for Rs 435. The cost price of the article is
(a) Rs 520
(b) Rs 530
(c) Rs 540
(d) Rs 550
Solution:
(b) Rs 530
Let the $\mathrm{CP}$ be Rs $x$.
Then, we have:$625-x=\mathrm{x}-435$
$\Rightarrow x+x=625+435$
$\Rightarrow 2 x=1060$
$\therefore x=\operatorname{Rs} 530$
