Answer 2

Answer:

Case1: 400ml bottle costs Rs 220

Cost of 1ml = 400/220 = Rs 1.818

Cost of 100 ml = 1.818 * 100 = Rs 181.8

Case2: 500ml bottle costs Rs 270

Cost of 1 ml = 500/270 = Rs 1.851

Cost of 100 ml = 1.851 * 100 = Rs 185.1

Therefore, no monetary advantage gained in buying the 500 ml bottle as it is charging 4 Rs more for every 100 ml.
