The pair of averages whose value can be determined graphically.(a) Mean and Median(b) Mode and Mean(c) Mode and Median(d) None of these

The pair of averages whose value can be determined graphically is (a) Mean and Median.

Here's why:

1. Mean: The mean is the average of a data set and can be represented graphically. For example, if you plot a data set on a number line, the mean would be the point that balances the line. If you were to balance the number line, the mean would be the fulcrum point.

2. Median: The median is the middle value of a data set when it is ordered from least to greatest. This can also be represented graphically. For example, if you plot a data set on a number line, the median would be the point that divides the line into two equal halves.

On the other hand, the mode, which is the most frequently occurring value in a data set, is not easily represented graphically. Therefore, options (b) and (c) are not correct.
