Answer 1

Answer:

Step-by-step explanation:

First find the surface area of the cylinder. We will get it as 1319.47 cm2.

To find the cost of delux paint =

200 x 13.1947 / 100 = 2638.94 ml

= 2638.94 / 1000 = 2.63894 l

Per liter cost = Rs. 400

Cost = 2.63894 x 400

= Rs. 1055.576

For super delux paint:

120 cm2 = 200ml

Surface area = 1319.47 cm2

ml = 1319.47 x 5/3 = 2199.117

= 2199.117 / 1000 = 2.199117 l

Cost per liter = 450

= 450 x 2.199117

= Rs. 989.60265
