Answer :

Given:

Height of cone (h) = 35 cm


Radius of one end (r1) = 30 cm


Radius of other end (r2) = 12 cm


Price = Rs 40/litre







Capacity of container = 110×468


Capacity of container = 51,480 cm3



Capacity of container = 51.48 litres


Now,


Cost of 1 litre milk = Rs 40


Cost of 51.48 litres milk = Rs 40 × 51.48 = Rs 2059.20


If he sells half the milk at half the rate,



Quantity of half the milk = 25.74 litres


Cost of 25.74 litres @ Rs 20 = Rs 25.74 × 20 = Rs 514.80


Cost of 25.74 litres @ Rs 40 = Rs 25.74 × 40 = Rs 1029.60


Total Cost = Rs 514.80 + Rs 1029.60 = 1544.40


Hence,


Capacity of container = 51.48 litres


Total Amount he received = Rs 2059.20


Total Cost (if he sell half milk at half the rate) = 1544.40
