The correct option is D 25%
Let the cost price (CP) of 15 articles be ₹100
CP of 1 article = ₹10015
Selling price (SP) of 12 articles = ₹100
SP fo 1 article = ₹10012
SP > CP
∴ Profit on 1 article = ₹ 10012−₹10015
= ₹ 500−40060
= ₹ 10060
∴ Profit percent = ProfitCP×100
= 1006010015×100
= 10060×1510×100
= 25%
Hence, profit = 25%
