Solution :
Given:
Ashok bought 144 items at 90 paise each and 20 items broke.
He sells the rest at Rs. 1.20 each.
We know,
Profit percentage = $\frac{\text{Selling price – Cost price}}{\text{Cost price}}$ × 100
20 items are broken out of 144 items.
Cost price of 144 items = $\frac{144 × 90}{100}$ = Rs. 129.6
Total selling price = 1.20 × 124 = Rs. 148.8
Gain = 148.8 – 129.6 = Rs. 19.2
Gain percentage = $\frac{19.2}{129.6}$ × 100 = 14.8%
Hence, the correct answer is 14.8%.
