Question

An electronic goods dealer purchased a second hand colour T.V for Rs.7250. He spent Rs. 250 on its repair and sold it for Rs.7800. Find his gain or loss percent.

Answer 1

C.P of the television $=Rs.7250$
Overhead (repair) charges $=Rs.250$
Total cost of the T.V $=Rs.(7250+250)=Rs.7500$
S.P of the T.V $=Rs.7800$
$\therefore Gain=Rs.7800-Rs.7250=Rs.300$
$\therefore Gain\%=\frac{Totalgain\times 100}{C.P}=\frac{300\times 100}{7500}=4\%$
