if a and b are mixed in 3 5 ratio and b and c in 8 5 ratio if the

Since a:b=3:5 and b:c=8:5, then a:b:c=24:40:25.
So b's qnty. in 35 litres of mixture=40/89*35
=15.73 litres

a & b are in ratio=3:5----(1)
b& c are in ratio=8:5----(2) so,
take the l.c.m for b's ratio on both ,get 40 (5*8)
convert the ratio with 40 as lcm,get
(3*8):(5*8):(5*5)=24:40:25
amount of b=35*(40/(24+40+25))
=15.73

so,the amount of b is 15.73

ans =15.730L
first given a:b=3:5
and b:c=8:5
therefore a:b:c=24:40:25
now from question 24x+40x+25x=35L
89x=35000mL
x=393.25 mL
Now amount of b=40x
b=40*393.25mL
b=15.730L

a:b:c
3:5
8:5
Total part 3+5+8+5=21
Part of b =13
35/21*13=21.7

The amount of b is 21.7

now firstly find a:b:c
So
a:b
b:c
3:5
8:5
a:b:c=24:40:25
so b's part is=40*35/89=15.73

since a:b=3:5--(1)
& b:c=8:5--(2) & also a+b+c=35--(3)
on solving all 3 eq. for b,,we got b=15.73

if a and b are mixed in 3:5 ratio and b and c in 8:5 ratio if the final mixture is 35 litres,find amount of b?
