Correct Answer: 1 : 1
Solution : Let the total number of donors be $a$. Number of donors of blood group '$O$' = $\frac{80°}{360°}\times a$ Number of donors of blood group '$A$' = $\frac{90°}{360°}\times a$ Number of donors of blood group '$AB$' = $\frac{70°}{360°}\times a$ Average of the number of donors of blood groups ' $\mathrm{A}$ ' and ' $\mathrm{AB}$ ' together = $\frac{1}{2}\times ( \frac{90°}{360°}\times a+\frac{70°}{360°}\times a)$ = $\frac{80°}{360°}\times a$ So, the Ratio of the number of donors of blood group ' $O$ ' to the average of the number of donors of blood groups ' $\mathrm{A}$ ' and ' $\mathrm{AB}$ ' together = $\frac{80°}{360°}\times a:{\frac{80°}{360°}\times a}$ = 1 : 1 Hence, the correct answer is 1 : 1.
