Shopkeeper purchased 300 bulbs for ₹3000
If 10 bulbs were fused, the cost of 10 bulbs is ₹100
If he sell 290 bulbs as ₹12 each = 290×12 =3480
when he sell the the cost of each bulb as ₹12 he got ₹480 profit
As a percentage = 480÷3000×100=16
so he got 16% profit

A shopkeeper purchased 300 bulbs for Rs 10 each. However 10 bulbs were...
To find the gain or loss percentage, we need to calculate the cost price (CP) and selling price (SP) of the bulbs.
1. Cost Price Calculation:
The shopkeeper purchased 300 bulbs for Rs 10 each, so the total cost price of the bulbs is:
CP = 300 bulbs × Rs 10/bulb
= Rs 3000
2. Selling Price Calculation:
Out of the 300 bulbs, 10 bulbs were fused and had to be thrown away. Therefore, the shopkeeper was able to sell only (300 - 10) = 290 bulbs.
The selling price of each bulb is Rs 12, so the total selling price of the bulbs is:
SP = 290 bulbs × Rs 12/bulb
= Rs 3480
3. Gain or Loss Calculation:
To calculate the gain or loss percentage, we use the formula:
Gain or Loss % = (SP - CP)/CP × 100
Substituting the values we have:
Gain or Loss % = (3480 - 3000)/3000 × 100
= 480/3000 × 100
= 16%
Therefore, the gain or loss percentage is 16%. Option C is the correct answer.
