x=total numver of fruit  O=(x/3)   ...(i)  M=(1/5)×(x−(x/3))=((2x)/(15))    ...(ii)  (B/P)=(5/3)    ...(iii)  P=O−8   ...(iv)  O+M+B+P=x   ...(v)    P=O−8=(x/3)−8  B=((5O)/3)=(5/3)((x/3)−8)  ⇒(x/3)+((2x)/(15))+(5/3)((x/3)−8)+(x/3)−8=x  ⇒x=60  O=20  M=8  P=12  B=20
$${x}={total}\:{numver}\:{of}\:{fruit} \\ $$$${O}=\frac{{x}}{\mathrm{3}}\:\:\:…\left({i}\right) \\ $$$${M}=\frac{\mathrm{1}}{\mathrm{5}}×\left({x}−\frac{{x}}{\mathrm{3}}\right)=\frac{\mathrm{2}{x}}{\mathrm{15}}\:\:\:\:…\left({ii}\right) \\ $$$$\frac{{B}}{{P}}=\frac{\mathrm{5}}{\mathrm{3}}\:\:\:\:…\left({iii}\right) \\ $$$${P}={O}−\mathrm{8}\:\:\:…\left({iv}\right) \\ $$$${O}+{M}+{B}+{P}={x}\:\:\:…\left({v}\right) \\ $$$$ \\ $$$${P}={O}−\mathrm{8}=\frac{{x}}{\mathrm{3}}−\mathrm{8} \\ $$$${B}=\frac{\mathrm{5}{O}}{\mathrm{3}}=\frac{\mathrm{5}}{\mathrm{3}}\left(\frac{{x}}{\mathrm{3}}−\mathrm{8}\right) \\ $$$$\Rightarrow\frac{{x}}{\mathrm{3}}+\frac{\mathrm{2}{x}}{\mathrm{15}}+\frac{\mathrm{5}}{\mathrm{3}}\left(\frac{{x}}{\mathrm{3}}−\mathrm{8}\right)+\frac{{x}}{\mathrm{3}}−\mathrm{8}={x} \\ $$$$\Rightarrow{x}=\mathrm{60} \\ $$$${O}=\mathrm{20} \\ $$$${M}=\mathrm{8} \\ $$$${P}=\mathrm{12} \\ $$$${B}=\mathrm{20} \\ $$
