A buys oranges at Rs. 2 for 3 oranges and sells them at a rupee each. To make a profit of Rs. 10, he must sell?
Correct Answer: 30 oranges
Explanation:
Suppose he sells x oranges
Then, C.P.of x oranges = Rs. 2x/3
S.P. of x oranges = Rs. x
Profit on x oranges = Rs. (x - 2x/3) = Rs. x/3
∵ x/3 = 10 ⇒ x = 30
