UP Police Constable Exam Model Paper 5

Given:
A dealer sold a radio at a profit of $22\%$. Had he sold it for INR 200 less, he would have gained a profit of $17\%$
Calculation:
Earlier profit of $22\%$, now profit of $17\%$ if sold for INR 200 less.
Thus, $22\%-17\%=\mathit{I}\mathit{N}\mathit{R}200$
$\Rightarrow 5\%=\mathit{I}\mathit{N}\mathit{R}200$
$\Rightarrow 1\%=\mathit{I}\mathit{N}40$
$\mathit{C}\mathit{P}=100\%=\mathit{M}\mathit{R}4000$
Thus, original selling price of radio $=4000\times 122∕100=\mathit{I}\mathit{N}\mathit{R}4880$
$\therefore$ Original selling price of radio is INR 4880
