Given: Profit of 1 bag of white cement = ₹ 8 And Loss of 1 bag of grey cement = ₹ 

(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.
