Correct Answer: $63:188$


Solution : The central angle for each sector corresponds to its sale. So, find the average in terms of the central angle.
Average of sales of A and B = $\frac{18º + 45º}{2}$
= $\frac{63º}{2}$
Average of sales of D and E = $\frac{120º + 68º}{2}$
​= $\frac{188º}{2}$
Required Ratio = $\frac{63º}{2}$: $\frac{188º}{2}$ = $63: 188$
Hence, the correct answer is $63:188$.
