AI explanation

Let the cost price of one toy be Rs. x. By selling 18 toys, the total selling price is 16800, and the gain is the cost price of 3 toys, which is 3x. The total cost price of the 18 toys is 18x, so using the profit formula, 16800 equals 18x plus 3x, giving 16800 = 21x. Solving for x gives 800, so the cost price of a toy is Rs. 800.
