Correct Answer: 40%
Solution :
Let the cost of one item be Re. 1.
$\therefore$ Cost of 100 items will be Rs. 100.
As 15% of the items went bad,
Remaining items = 100 – 15 = 85
Overall profit = 19%
⇒ Selling price $= \frac{\text{Cost price}\times \text{Profit}\%}{100}+\text{Cost price}$
⇒ Selling price $= \frac{100\times19}{100}+100$
⇒ Selling price $= 19 +100$
⇒ Selling price $= 119$
Now, 85 items must be sold for Rs.119.
Profit = Selling price – Cost price $= 119 - 85 = 34$
$\therefore$ Profit % $= \frac{34}{85}\times 100 = 40$%
Hence, the correct answer is 40%.
