A fruit seller buys 240 apples for Rs 600. Some of these apples are bad and are thrown away. He sells the remaining apples at Rs 3.50 each and makes a profit of Rs 198. What percentage of the apples was thrown away?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 5%
The money he received equals cost price \(+\) profit. Dividing it by the price of one apple gives the number of apples sold; the rest were thrown away.
Money received \(=600+198=\) Rs 798
Apples sold \(\displaystyle =\frac{798}{3.50}=228\)
Apples thrown away \(=240-228=12\)
Percentage thrown away \(\displaystyle =\frac{12}{240}\times100=5\)%
5% of the apples were thrown away.
