Ex 3.1, 1 A merchant in the port city of Lothal is exchanging bags of spices for copper ingots. He receives 15 ingots for every 2 bags of spices. If he brings 12 bags of spices to the market, how many copper ingots will he leave with? Given that he receives 15 ingots for every 2 bags of spices Thus, Cost of 2 bags of spices = 15 ingots And, we can write Cost of 1 bag of spices = 𝟏𝟓/𝟐ingots Now, we need to find cost of 12 bags of spices Thus, Cost of 12 bag of spices = 12 × Cost of 1 bag of spices = 12 × 𝟏𝟓/𝟐 ingots = 6 × 15 = 90 ingots Thus, the merchant will leave with 90 copper ingots.
