Question
Find the difference between the average no. of cars sold
by V in all the 3 Qrtrs to the total no. of cars sold by Y in all 3 Qrtrs?Solution
Average no. of cars sold by V in all the 3 Qrtrs =(25+125+150)/3 = 300/3 = 100 Number of cars sold by Y all 3 Qrtrs = 50 + 150 + 75 = 275 Required difference = 275 - 100 = 175
