Hi there,

Following pls find the worked solution:

M : 1 1/5 = 6/5; S = 1
So M = 6u; S = 5u

M: 80% --> 6u
B: 100% --> (6 / 80) x 100 = (15/2)u

M : S : B
6 : 5 : (15/2)
12 : 10 : 15

Total = 12u + 10u + 15u --> 11100
37u --> 11100
1u --> \$300
S = 10u --> 10 x 300 = \$3000

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

Do let me know if this does not agree with the answerkey..

Cheers,
Edward
