5)

B+A - B+R = Diff of A and R

A : R : Diff
5 : 7 : 2

2u --> 6000-4800
= 1200

1u --> 1200÷2
= 600

5u (A's amt.) --> 600×5
= 3000

B's amt. --> 4800-3000
= 1800

Ans: $1800

6)

M+R --> 450×2
= 900

M+J --> 240×2
= 480

R : J : Diff
5 : 2 : 3

3u --> 900-480
= 420

1u --> 420÷3
= 140

2u (J's amt.) --> 140×2
= 280

M's amt. --> 480 - 280
