A factory buys 8 machines. 3 MachineA, 4 MachineB and rest MachineC. Prices of the machines are Rs 45000, Rs 25000 and Rs 35000 respectively. Calculate the average cost (in Rs) of these machines?
Cost of machines A, B and C respectively are : Rs. 45000 , 25000 and 35000
Number of machines A, B and C respectively are : 3 , 4 , 1
=> Total cost = $$(3 \times 45000) + (4 \times 25000) + (1 \times 35000)$$
= 135000 + 100000 + 35000 = Rs. 2,70,000
$$\therefore$$ Average cost = $$\frac{2,70,000}{8}$$ = Rs. 33,750
=> Ans - (A)
