Given: Profit of 1 bag of white cement = ₹8 And Loss of 1 bag of grey cement = ₹5
(a) Profit on selling 3000 bags of white cement = 3000 x 8 =₹24,000
Loss of selling 5000 bags of grey cement = 5000 x 5 = ₹25,000
Since Profit < Loss
Therefore, his total loss on selling the grey cement bags = Loss – Profit = 25,000 – 24,000 = $ ₹1,000
Thus, he has lost of ₹1,000 on selling the grey cement bags.
(b) Let the number of bags of white cement be x. According to question, Loss = Profit
Thus, he must sell 4000 white cement bags to have neither profit nor loss.
