The table below gives the numbers of students from five different colleges who participated in Olympiads of five different subjects during a given year.

Find the difference between 'the range of the numbers of participants in the different Olympiads from College C' and 'the average number of participants per Olympiad from College E' during the given year.

38

We know ,

Range = Highest number - Lowest number

The range of the numbers of participants in the different Olympiads from College C

= 250 - 80

= 170

Average number of participants per Olympiad from College E

= \(\frac{112 + 105 + 180 + 80 + 183 }{5}\)

= \(\frac{ 660}{5}\)

= 132

Required difference = 170 - 132 = 38
