Answer 1

I) from buyers perspective,

case 1

1dozen (=12 bananas) cost Rs 30

cost of 1 banana= 30/12= rs 2.50

case 2

1 score(=20 bananas) cost rs 40

cost of 1 banana= 40/12= rs 3.33

therefore case 1 is better

ii) assuming that more distance in less time is better,

case 1

5 hr= 240 km

1hr= 48 km

case 2

4 hr= 180 km

1hr= 45 km

case 2 is better
