The cost price of pulses is 12% less than the selling price. Using a faulty weighing machine, shopkeeper is able to earn 25% profit. How much per cent of the faulty machine shows more weight as compared to the actual weight (Rounded off to the nearest integer)?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 10%
Profit = SP - CP
Profit % = (profit/CP) × 100
Let the selling price be 100x
Cost price = 88% of 100x = 88x
We know that, shopkeeper is able to earn 25% profit
Total selling price = 125% of 88x = 110x
Hence, required percent more faulty machine showed = [(110x - 100x)/100x] × 100
⇒ 10%
