By selling 15 balls for ₹1,220, there is a loss equal to the purchase price of 5 balls. What is the cost price (in ₹) of one ball?
15 गेंदों को ₹1,220 में बेचने पर, 5 गेंदों के क्रय मूल्य के बराबर हानि होती है। एक गेंद का क्रय मूल्य (₹ में) ज्ञात कीजिए।
Detailed Solution & Logic
Correct Answer:
₹122
Let the cost price of one ball be ₹$x$.
Cost price of 15 balls $=15x$
Loss = Cost price of 5 balls $=5x$
Selling price $=15x-5x=10x$
$10x=1220$
$x=122$
Hence, the cost price of one ball is ₹122.
