A man buys some apples at the rate of 36 for Rs 1. How many apples should he sell for Rs 1 to gain a 44% profit?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 25
The money from a set of apples must be 144% of their cost. For Rs 1 he must therefore hand over apples that cost him only \(\displaystyle \frac{100}{144}\) rupee.
Rs 1 buys 36 apples, so each apple costs \(\displaystyle \frac{1}{36}\) rupee
Cost of the apples sold for Rs 1 \(\displaystyle =\frac{100}{144}\) rupee
Number of apples \(\displaystyle =36\times\frac{100}{144}=25\)
Check: 25 apples cost \(\displaystyle \frac{25}{36}\) rupee, and \(\displaystyle \frac{25}{36}\times1.44=1\) rupee
He should sell 25 apples for Rs 1.
