Answer» Answer: __________________________________ (I) Batting average in the first innings $= \frac{sum \: of \: the \: first \: innings \: scores}{number \: of \: first \: innings \: played}$ $= \frac{32 + 11 + 0 + 46 + 23 + 14}{6} = \frac{126}{6} = 21$ Batting average in second innings $= \frac{9 + 28 + 12 + 54 + 13 + 63}{6} = \frac{179}{6} = 29.83$ Thus, Aditya's batting average was better while playing in the second innings. (II) Average of first 3 MATCHES $= \frac{total \: runs \: scored \: in \: the \: frst \: 3 \: matches}{3}$ $= \frac{41 + 39 + 12}{3} = \frac{92}{3} = 30.6$ Average of last 3 matches $= \frac{total \: runs \: scored \: in \: last \: 3 \: matches}{3}$ $= \frac{100 + 36 + 77}{3} = \frac{213}{3} = 71$ Thus, he batted better in the last three matches. (III) Batting average for the last 6 matches $= \frac{total \: runs \: scored \: in \: the \: last \: 6 \: matches}{6}$ $= \frac{305}{6} = 50.83$ ___________________________________ •We have seen that: $average = \frac{sum \: of \: measures \: }{number \: f \: measures}$ The FOLLOWING two formulas can be EASILY derived from the above formula : Sum of measures = Average × Number of measures Number of measures $= \frac{sum \: of \: measures}{average}$ * The average is ALSO called the MEAN or the Arithmetic Mean. ****************************************************
