A vendor started selling vegetables at ₹10 per kg, but couldn’t find buyers at this rate. So he reduced the price to ₹7.2 per kg, but uses a faulty weight of 900 g instead of 1 kg. Find the percentage change in the actual price.

Question

Accepted Answer

Step 1: Original price per kg = ₹10
Step 2: New price per kg = ₹7.2
Step 3: Faulty weight used = 900 g instead of 1000 g

Step 4: Calculate the actual price per kg when selling at ₹7.2 per 900 g:
Price per gram = 7.2 / 900 = ₹0.008 per gram
Price for 1000 g (1 kg) = 0.008 × 1000 = ₹8

Step 5: Calculate the percentage change in actual price:
Percentage change = ((New price - Original price) / Original price) × 100
= ((8 - 10) / 10) × 100 = (-2 / 10) × 100 = -20%

The negative sign indicates a decrease. So, the actual price decreased by 20%.
