A shopkeeper buys 144 items at 90 paise each. On the way 20 items are broken. He sells the rest at ₹1.20 each. His gain per cent correct to one place of decimal is:

13.8% 14.6% 14.8% 15.8%

14.8%

C.P. = 144 × \(\frac{90}{100}\) = Rs. 129.6 S.P. = (144 - 20) × 1.20 = Rs. 148.8 Profit = 19.2 Profit % = \(\frac{19.2}{129.6}\) × 100 = 14.8%
