- 3:5 8:5
24:40 40:25
so a:b:c::24:40:25
so b=35*40/89=15.73 ans - 11 years agoHelpfull: Yes(66) No(2)
- a:b=3:5 ......1
b:c=8:5 ......2
a:b=24:40 since (1)*8
b:c=40:25 since (2)*5
a:b:c=24:40:25
let a=24x,b=40x,c=25x
mixture=(24x+40x+25x)=35 ltr
x=35/89
hence b=40*35/8915.73 ltr - 11 years agoHelpfull: Yes(15) No(0)
- a:b = 3:5
b:c = 8:5
so a:b:c = 24:40:25
so amount of b = 40*35/(24+40+25) = 15.73 liters - 11 years agoHelpfull: Yes(12) No(0)
- a:b=3:5
b:c=8:5
a:b:c=(3*8):(5*8):(5*5)
b=40*35/89 - 11 years agoHelpfull: Yes(2) No(0)
- given
a+b+c=35
a/b=3/5.....so,a=3*b/5
b/c=8/5........so,c=5*b/8
put the value of 'a' and 'c' in a+b+c=35
u get,
b = 1400/89 =15.73 - 11 years agoHelpfull: Yes(2) No(0)
- 3:8*(5/8):5*(5/8)
24:40:25
b=(35*40)/89 - 11 years agoHelpfull: Yes(1) No(0)
- a/b=3/5, b/c=8/5,, b/c=5*8*1/5*8/5*1/40
b/c=5/5/40,,,,, therefor a:b:c= 3:5:5/40 = 120:200:5
b=200/325*35=21.5 - 11 years agoHelpfull: Yes(0) No(8)
- after solving the equations the value we get is b=35*40/89.
