8. (4) A का ( 20 %=B ) का ( 30 %=C ) का ( frac{1}{6} ) ( Rightarrow frac{20 mathrm{A}}{100}=frac{30 mathrm{B}}{100}=frac{mathrm{C}}{6} ) ( Rightarrow frac{A}{5}=frac{B}{frac{10}{3}}=frac{C}{6}=k(text { माना }) ) ( Rightarrow A=5 k, B=frac{10}{3} k, C=6 k ) ( therefore A: B: C=5 k: frac{10 k}{3}: 6 k ) ( =15: 10: 18 )
