Question

Harish bought a second-hand printer for $1200$ and spent $200$ on its repairs. He sold it for $1680$. Find his profit or loss in percent.

Answer 1

Total cost price $=1200+200=1400$ Rs.

Selling price = Rs. $1680$

Gain $=1680-1400=280$

Therefore, gain percent = $\frac{gain\times 100}{C.P.}$

= $\frac{280\times 100}{1400}$ = $20$ %
