Need help again for this P4 qtn. Saw from last year’s posting but could not understand the workings without models.


Matthew and Paul have a sum of money at first. If Matthew gives Paul $80, he will have twice as much as Paul. If Matthew gives Paul $20, he will have thrice as much as Paul. How much money did Matthew have at first?

Thanks!
