2.Jill's weekly income was 130% of Bill's weekly income.
Bill's weekly income is how much percentage of jill's weekly income?

Solution
Such problems are available in R.S Agarwal.
If Jill’s weekly income was 30% (If Jill earns 13$ n Bill earns 10$ then Jill earns 30% more than Bill i.e. Jill earns 130% of Bill's earning) more than Bill then Bill is less than Jill by [30/(100+30)*100]% , this gives how much lesser Bill earns than Jill, subtract this from 130% n that gives answer.(This is my guess, if some one could come with more better solution ,we will put it here)
