A man buys oranges at ₹5 a dozen and an equal number at ₹4 a dozen. He sells them at ₹5.50 a dozen and makes a profit of ₹50. How many dozen oranges does he buy?
A
30 dozen
B
40 dozen
C
50 dozen
D
60 dozen
Correct Option:
C
Explanation
Equal quantities are bought at ₹5 and ₹4 per dozen, so the average cost price is ₹4.50 per dozen. The selling price is ₹5.50, giving a profit of ₹1 per dozen. A ₹50 profit therefore corresponds to 50 dozen.
