Detailed Solution

Concep- We will first determine the cost price of one toy from the cost price of a dozen toys in order to determine the gain %. The difference between the cost price and the selling price of the toy will then be used to calculate the profit. Then, in order to determine the profit %, we substitute the cost price and profit values in the expression.
Cost Price of 1 toy = Rs. 375 12 =   Rs. 31.25
According to question, selling Price of 1 toy = Rs. 33
So Gain = Rs. (33−31.25)=   Rs.1.75
Profit %= 1.75 31.25 ×100%= 28 5 %=5.6%  
Hence, the correct answer is option 3.
