Question
A dealer has 3000 kg of pulses. He sells a part of it at
22% profit and the rest at 14% profit. If the overall gain is 18%, determine how much (in kg) was sold at 14% profit.Solution
Let the quantity of pulses sold at 22% profit be z kg.
Then, the quantity sold at 14% profit = 3000 - z kg.
Thus, the quantity of pulses sold at 14% profit = 3000 - 1500 = 1500 kg ..
