Racers at a 5k race are assigned an identification tag consisting of two digits (0–9) and one letter. how many different identification tags are possible?

The different identification tags which are possible are:

                    2600

It is given that the tag is to be assigned such that it consists of two digits (0-9) and one letter.

Since there are a total of 10 digits and 26 alphabets.

This means that the number of different tags that could be possible are:

                10×10×26=2600

( Since any one of the 10 digits could come up in two places and any one of the 26 alphabets could come up)

             Hence, the answer is:

                    2600

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
