Question
The numbers 4,6,10, x, 20,24,32 is arranged in ascending
order. Find the value of x if their mean and their median are equal.Solution
Median of 4, 6, 10, x, 20, 24, 32 is x. Mean = (4+6+10+x+20+24+32)/ 7 Now, according to question, Mean = Median (4+6+10+x+20+24+32)/7 = x (96 + x) = 7x 6x =96 X = 96/ 6 = 16 Hence, the value of x is 16.
