$\huge \bf \underline{ \underline{Question}}$

A merchant bought 1000 electric bulbs at the rate of Rs. 150 each. 50 of them were broken on the way and the remaining he sold at the profit of 5%. What was the selling price of each bulb?

$\huge \bf \underline{ \underline{Answer}}$

Given:-

• No. of electric bulbs = 1000
• cost of each electric bulb = ₹ 150
• No. of bulbs broken = 50
• Selling price of each bulb = $x$
• Profit percentage = 5%

To Find:-

The selling price of each bulb.

Solution:-

Cost price of 1000 electric bulbs,

= 1000 × ₹150

= ₹1,50,000

5% profit on the total cost price,

$= \frac{5}{100} \times ₹150000 \\ = ₹7500$

Total selling price = ₹157500

No. of bulbs remaining = 950

Therefore, selling price of each bulb,

$= \frac{₹157500}{950} \\ = ₹165.79$

Therefore,

Selling price of each bulb = ₹165.79
