Answer:
Let the cost price of the item be x rupees.
If the cost price of the item is Rs. x, then a 20% profit on this cost price is given as:
20% of x = 0.20 * x
The selling price of the item, including a 20% profit, would be the cost price plus the profit:
Selling price = Cost price + Profit
Selling price = x + 0.20x
Selling price = 1.20x
According to the problem, the selling price is Rs. 4.00.
So, 1.20x = Rs. 4.00
To find the cost price (x):
x = Rs. 4.00 / 1.20
x = Rs. 3.33 (approximately)
Therefore, the cost price of the item is approximately Rs. 3.33.
