A woman bought a grinder for N60,000. She sold it at a loss of 15%. How much did she sell it?

A.

N53,000

B.

N52,000

C.

N51,000

D.

N50,000

Correct answer is C

SP = Nx
CP = N60,000
Percentage loss = 15%
Using percentage loss...

\(\frac{CP - SP}{CP} = \text{100%}\)

\(\text{15%} = \frac{60000 - x}{60000} \times \text{100%}\)

\(\text{15%} \times 60000 = (60000 - x)\text{100%}\)

\(60000 - x = \frac{\text{15%} \times 60000}{\text{100%}}\)

60000 - x = 3 x 3000

60000 -x = 9000

x = 60000 - 9000

x = N51,000
