If the mean of numbers 38, x, 70, 88 and 110 is 69, what is the mean of 50, 72, 97, 125,147 and x? Choose the correct choice from the following
A) 73.5
B) 77.86
C) 86.67
D) 66.69
E) 70.56
Mean = (Sum of all no. in series)/(no. in series)   M1 = 69 = (X+38+70+88+110)/(5)   69 x 5 = 290 + X   X = 39   Therefore mean of 2nd series   M2 = (X+50+62+97+125+147)/6   M2 = 86.67   Answer = 86.67
