A fruit merchant bought some bananas. One Fifth of them got rotten and were thrown away. He sold two fifth of the bananas with him at 15% profit and the remaining bananas at 10% profit. Find his overall loss or profit percent?
Answer & explanation
Correct answer: option 2
Let bananas cost to Rs.100
If one fifth bananas are rotten then,
Remaining bananas = 80%
80% bananas cost Rs. 80.
Total profit percentage on them = \(\frac{2}{5}\) × 15 + \(\frac{3}{5}\) × 10 = 12%
SP of bananas = 80 × \(\frac{112}{100}\) = 89.6
Loss = 100 - 89.6 = 10.4
Loss% = \(\frac{10.4}{100}\) × 100 = 10.4%
