A:B = 6:4, B:C = 1:4. Now if C is 38, what is A?
Read Solution (Total 13)
-
- b/c=1/4 && c=38
so b=c/4 => b=19/2
a=6b/4 => so a=57/4 => 14.25 - 10 years agoHelpfull: Yes(26) No(0)
- B:C=1:4
let the material in B:c ne x
C is given =38
4x/5=38
x=47.5
B=9.5
now find A from A:B=6:4
4x/10=9.5
x=23.75
A=x-B=23.75-9.5=14.25
A=14.25

- a:b=6:4 b:c=1:4
a:b:c=6:4:16=3:2:8
8*x/13=38 here x is total value. x=38*13/8
now a is
(x/13)*3=[(38*13)/(13*8)]*3=14.25

- A/B=6/4, B/C=1/4
C=38
THEREFORE B=38/4=9.5
A=(9.5*6)/4=14.25 - 10 years agoHelpfull: Yes(3) No(0)
- A:B:C=6:4:16 ,A=14.25
- 10 years agoHelpfull: Yes(1) No(0)
- b/c=1/4
c=38
so b=c/4 => b=19/2
a=6b/4 => so a=57/4 => 14.25

- A : B B : C
6 : 4 1 : 4
4 : 16
therefore A:B:c = 6:4:16
so if A:C is 6:16
and if C is 38 then A is 57/4; - 9 years agoHelpfull: Yes(0) No(0)
- a:b=6:4 b:c=1:4
a:b:c=6:4:16
=>a:b:c=3:4:8
given cx=38 =>8x=38 =>x=38/8
=>ax=3*38/8=14.25 - 9 years agoHelpfull: Yes(0) No(0)
- A:B:C=6:4:16
A=6x,B=4x,C=16x
16x=38
x=38/16
A=6*(19/8)
A=57/4 - 9 years agoHelpfull: Yes(0) No(0)
- B/C=1/4
4B=C
4B=38
B=38/4
B=9.5
A/B=6/4
4A=6B
4A=6*9.5
A=14.25 - 9 years agoHelpfull: Yes(0) No(0)
- A is 19
A:2B:C=2:1:4
B:C=1:4 sub C=38 then B=19/2
A:B:C=x:19/2:38
if x=19 then
A:B:C=19:19/2:38=1:1/2:2=2:1:4
so A=19 - 5 years agoHelpfull: Yes(0) No(0)
