Question
If a shopkeeper buys toys at a price ranging from Rs.
175 to Rs. 200 and sells at prices ranging from Rs. 275 to Rs. 300, what is the maximum possible profit that might be made in selling 45 toys?Solution
To make the maximum possible profit, one has to purchase the toys at minimum rate and he must sell the same at maximum rate. C.P. of 45 toys at minimum rate = 45 
 175 = Rs.7, 875 and S.P. of 45 toys at maximum rate = 45  300 = Rs. 13,500 ∴ Maximum possible profit = 13,500 – 7,875 = Rs. 5,625
