Cost of machines A, B and C respectively are : Rs. 56000 , 45000 and 30000 Number of machines A, B and C respectively are : 2 , 4 , 1 => Total cost = $$(2 imes 56000) + (4 imes 45000) + (1 imes 30000)$$ = 112,000 + 180,000 + 30,000 = Rs. 322,000 $$ herefore$$ Average cost = $$frac{3,22,000}{7}$$ = Rs. 46,000 => Ans - (A)
