A vendor buys 20 apples for Rs. 300 and sells them at 15 for Rs. 300. How many apples should be bought and sold to earn a profit of Rs. 300?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 60
Given that
The cost of 20 apples is Rs. 300
C.P. = 300/20 = 15 Rs per apple
He sells them at 15 for Rs. 300.
S.P. = 300/15 = 20 Rs per apple
the profit = S.P. - C.P. = 20 - 15 = 5 Rs per apple
Hence, he bought and sold the apples to get Rs 300 as profit = 300/5 = 60 apples
