Misc 4 A manufacturer makes two types of toys A and B. Three machines are needed for this purpose and the time (in minutes) required for each toy on the machines is given below: Each machine is available for a maximum of 6 hours per day. If the profit on each toy of type A is Rs 7.50 and that on each toy of type B is Rs 5, show that 15 toys of type A and 30 of type B should be manufactured in a day to get maximum profit. As we need to maximize the Profit Profit on Type A → Rs 7.50 Profit on Type B → Rs 5 ∴ Z = 7.50 x + 5y Combining all constraints : Max Z = 7.5x + 5y Subject to constraints, 2x + y ≤ 60, x ≤ 20, 2x + 3y ≤ 120, & x ≥ 0 , y ≥ 0 Hence, profit will be maximum if Number of Type A toys = 15 Number of Type B toys = 30 Maximum Profit = Rs. 262.50
