Answer:
16.67%
Step-by-step explanation:
Let the cost price of the fan be ₹z
Therefore one-sixth of the cost price =₹(1/6×z) = ₹z/6
Selling price of the fan = ₹644
B.T.P,
z + z/6 = 644
=>6z +z/6 = 644
=>7z/6 = 644
=> z = 644÷7/6
=> z = 644× 6/7
=> z = 92 × 6
=> z = 552
Therefore cost price = ₹552
Therefore gain = ₹(1/6 × 552) = ₹92
Therefore gain percentage = (92 × 100/552)%
= (100/6)% = (50/3)%
= 16.67%
