설명
Total Cost Price = N(250,000 + 70,000)
= N 320,000
Selling Price = N 400,000(Given)
Gain = Selling Price - Cost Price
= 400,000 - 320,000
= 80,000
% gain = \(\frac{\text{Gain}}{\text{Cost Price}}\) × 100
= \(\frac{80,000}{320,000}\) × 100
Gain % = 25%
= N 320,000
Selling Price = N 400,000(Given)
Gain = Selling Price - Cost Price
= 400,000 - 320,000
= 80,000
% gain = \(\frac{\text{Gain}}{\text{Cost Price}}\) × 100
= \(\frac{80,000}{320,000}\) × 100
Gain % = 25%
