Hi everyone! I am stuck with this maths question. May you help me? Please show your workings clearly.

Qn1. Leon, James, Paul and Gary shared $4900. Paul received 3 times as much as Gary received. James received 2/3 of the total amount of money that Paul and Gary received. Leon received 1/4 of the total amount of money that Paul, Gary and James received. How much more money did Paul received than Leon?

Thank you for you help.

Hi shirley,

Following pls find my worked solution :

P : G
3 : 1 -- (1)

J : (P+G)
2 : 3 -- (2)

L : (P+G+J)
1 : 4 -- (3)

Apply <restating problem> method, and comparing (1),(2), multiply (1) 3x; (2) 4x. And we have ...

P : G
9 : 3 -- (4)

J : (P+G)
8 : 12 -- (5)

Now, comparing (5),(3), multiply (3) 5x. We have ....

L : (P+G+J)
5 : 20 -- (6)

Given Leon (L), James (J), Paul (P) and Gary (G) shared $4900, we have ...

25u --> 4900
1u --> 196

P - L = 9u - 5u = 4u
4u --> 4 x 196 = $784

==============

Trust the above helps.

Do let me know again if this is different from your Answerkey or if theres further clarification.

Cheers,
Edward
