Answer Posted / vignesh
a/b=3/5,b/c=8/5.
a/(a+b)=3/8,b/(b+c)=8/13
a=((a+b)*3)/8-----1
(b+c)=13*b/8------2
a+b+c=35-----3
substituting the value 1&2 in 3
(((a+b)*3)/8)+13*b/8=35
finally we get
3a+16b=280-----4
solving one we get
5a-3b=0-----5
multiplying eqn 4 by 5 and eqn 5 by 3,we get,subtracting 4&5
15a+80b=1400
15a+9b=0
we get b=15.73
