Question

At what price should a stationary sell a box of crayons bought at Rs 17.50 so that he can make a profit of 18%

Answer 1

$\huge\boxed{\texttt{\fcolorbox{Red}{aqua}{Hey Mate!!!}}}$

C.P= ₹17.50

Profit% = 18%
$sp = cp( \frac{100 + profit\%}{100} ) \\ sp= cp( \frac{100 + 18}{100} ) \\ sp = \frac{1750 \times 118}{100 \times 100} \\ sp = 20.65$

Hope it helps.
