Answer 2

$<u>Answer :</u>$$<b><i>$

Number of bulbs purchased at Rs. 10 = 200

Purchase price = 200 × 10 = Rs. 2000

If 5 bulbs were defective, remaining bulbs = 195

Sale price = 12

Sale price of 195 bulbs = 195×12 = Rs. 2340

Profit = sale price – purchase price

= 2340 – 2000

= Rs. 340

$\sf\implies\dfrac{340}{2000}×100$

= 17%

∴ The gain percent is 17%
