Question -
Answer -
(a) Profit on one white cement bag = ₹ 8
loss on one grey cement bag = ₹ – 5
Profit on 3,000 bags of white cement
= ₹ (8 × 3,000) = ₹ 24,000
Loss on 5,000 bags of grey cement
= ₹ (-5 × 5000) = – ₹ 25,000
Total loss = – ₹ 25,000 + ₹ 24,000
= – ₹ 1000 i.e. ₹ 1000
(b) Selling price of grey bags at a loss of ₹ 5
= ₹ (5 × 6,400) – ₹ 32,000
For no profit and no loss, the selling price of white bags = ₹ 32,000
Rate of selling price of white bags at a profit of ₹ 8 per bag.
∴ Number of white cement bags sold
=32000/8=4000
Hence, the required number of bags = 4,000
