Question

Vikram bought $150$ dozens pencils at Rs.$10$ a dozen.His overhaead expenses were Rs.$100$.He sold them at Rs.$1.20$ each.What was his profit or loss percent?

Answer 1

Cost of one dozen pencil$=$Rs.$10$

Cost of $150$ dozen pencils$=$150\times$Rs.$10=$Rs.$150$

Overhead expenses$=$Rs.$100$

Effective cost price$=$Rs.1500+$Rs.$100=$Rs.$1600$

Selling price of one pencil$=$Rs.$1.20$

Selling price of one dozen pencil$=$Rs.$1.20\times 12=$Rs.$14.40$

Selling price of $150$ dozen pencil$=$Rs.$14.40\times 150=$Rs.$2160$

Here S.P$>$C.P.So, there is a profit.

Profit$=$S.P$-$C.P$=2160-1600=$Rs.$560$

Profit percentage$=\frac{Profit}{C.P}\times 100\%=\frac{560}{1600}\times 100\%=35\%$
