3) Peter, James and Ron shared to buy a box of chocolates. Peter paid 2/7 the total amount paid by James and Ron. Peter paid 3/4 the amount Ron paid. If Ron paid $8 more than Peter, how much money did James pay for the chocolates ?

Peter : Ron = 3:4
Peter : Ron & James = 2:7

Peter : Ron : James = 6: 8 : (21-8 ) = 6:8:13

8u – 6u = $8
2u = $8
1u = $4

James paid = 13u = 13 x $4 = $52 )[/quote]
Hi Dharma,

Thank you very much.

For qn 3, how do you get Peter : Ron : James = 6: 8 : (21-8 ) = 6:8:13 ?

Peter : Ron & James = 2 : 7 = 6 : 21

So, Peter : Ron : James = 6 : 8 : 13 (James portion is 21 – 8 = 13)
