Answer:

Concept :

Gain (G): The seller makes a profit when a product is sold for more than its cost price. For instance, if a plot was bought for Rs 50,000 and sold for Rs 1,50,000 three years later, there would be a profit of Rs 1 lakh. Loss (L): When a product is sold for less than its cost price, a loss is incurred by the seller. For instance, if a phone was purchased for Rs 20,000 and sold for Rs 12,000 a year later, the seller would have suffered a Rs 8000 loss.
