distribute 4950 among john, maria, and betsy, maria receives twice as much as john and betsy receives three times as much as maria

Answer 1

If J represents the amount John gets, then Marie gets 2J and Betsy gets 3*2J=6J. Since the 3 amounts combined make up the whole:

4950=J+2J+6J=9J -> 550=J

So John gets 550, Marie gets twice that or 1100 and Betsy gets 3 times that or 3300.
