Solution & Step-by-step Explanation

Given total number of machines = 7Number of Machine A = 2, Price per unit = Rs 95000 Number of Machine B = 2, Price per unit = Rs 75000 Number of Machine C = 7 - (2 + 2) = 3, Price per unit = Rs 43000 Total cost of all machines: Total Cost = (2 \times 95000) + (2 \times 75000) + (3 \times 43000) Total Cost = 190000 + 150000 + 129000 Total Cost = Rs 469000 Average cost of the machines: Average Cost = \frac{Total Cost}{Total Number of Machines} Average Cost = \frac{469000}{7} = 67000
