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 option: 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
