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:
Answer & explanation
Correct answer: option 3
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%
