Is the big bottle worth it?

Problem

The same juice comes in two bottles. Take the price and the liters of the small one (ps, ls) and the price and the liters of the big one (pb, lb). The big one almost always costs more in total, so that on its own says nothing: return true only if a liter comes out cheaper in the big bottle. If a liter costs the same in both, return false.

Examples

• 18, 1, 30, 2 → true

• 12, 1, 50, 3 → false

• Half a liter

  25, 1.5, 30, 2 → true

Besides these, the challenge has hidden tests that are revealed when you submit your solution.

You start with this

def worth_it(ps, ls, pb, lb):
    pass

function worthIt(ps, ls, pb, lb) {
}
