Q.A book seller sold 40 books at the price of ₹ 10 each. The total revenue of the seller is ______.

Total Revenue = Price × Quantity sold = 10 × 40 = ₹ 400, so the answer is option (c).

Total Revenue (TR) is the total receipts of a seller from selling a given quantity of a good. It is calculated as:

Total Revenue = Price per unit × Quantity sold

Here the price per book is ₹ 10 and the number of books sold is 40. So:

Total Revenue = 10 × 40 = ₹ 400

…

Revenue from the sale of an additional unit is marginal revenue.

The three revenue concepts are:

• Total Revenue (TR) = price × quantity sold.
• Average Revenue (AR) = TR ÷ quantity = price per unit.
• Marginal Revenue (MR) = the change in total revenue from selling one more unit (MR = TRₙ − TRₙ₋₁). …

Total Revenue = Price × Quantity = 10 × 40 = Rs. 400.

Total revenue (TR) is the total amount a seller receives from selling a given quantity of output, found by multiplying price per unit by the number of units sold.

Formula: TR = Price × Quantity

Given:

• Price per book = Rs. 10
• Number of books sold = 40

TR = 10 × 40 = Rs. 400.

…

Revenue from the sale of products is (c) total revenue.

Total Revenue (TR) is the entire amount of money a firm receives from selling its total output. It is calculated as:

TR = Price (P) x Quantity sold (Q)

For example, if a firm sells 100 units at a price of 10 each, TR = 10 x 100 = 1,000.

Why the others are wrong:

• (a) Marginal revenue is the addition to total revenue from selling one more unit, not the whole sale value. …
