LET $X BE THE AMONG OF B.2X+600+3X+X=5400
6X=4800
X=800
∴THE AMONG OF B IS $800
A IS $1600
C IS $3000

assuming A is x
2X=B
C+600=3B
C=3B-600
X+2X+3(2X)-600=5400
X=666.6666666666667.......
A=666.666666667
B=1333.3333333
C=1400
2X=B
C+600=3B
C=3B-600
X+2X+3(2X)-600=5400
X=666.6666666666667.......
A=666.666666667
B=1333.3333333
C=1400

2x+x+3x+600=5400
6x+600=5400
6x=4800
x=800
a=1600 b=800 c=3000
6x+600=5400
6x=4800
x=800
a=1600 b=800 c=3000

Explain:
All: $5400
=6B+$600
So B's amount is (5400-600)/6=4800/6=$800
A=2B so A's amount is $1600
C=3B+600
so C's amount is $3000
Answers:
A=$1600
B=$800
C=$3000
All: $5400
=6B+$600
So B's amount is (5400-600)/6=4800/6=$800
A=2B so A's amount is $1600
C=3B+600
so C's amount is $3000
Answers:
A=$1600
B=$800
C=$3000

A=2B
B=B
C=3B+600
A+B+C=5400
2B + B + 3B+600=5400
6B+600=5400
6B=4800
B=800
So..A=2 x 800
=1600
C=3 x 800 +600
=3000
B=B
C=3B+600
A+B+C=5400
2B + B + 3B+600=5400
6B+600=5400
6B=4800
B=800
So..A=2 x 800
=1600
C=3 x 800 +600
=3000
