If the mean of numbers 28, x, 70, 88 and 104 is 67, what is the mean of 50, 62, 97, 124 and x?  Select the correct option:
A) 76.5  B) 75.6  C) 73.5  D) 79  E) 77
Mean = (Sum of all no. in series)/(no. in series)   M1 = 67 = (X+28+70+88+104)/(5)   67 x 5 = 290 + X   X = 45   Therefore mean of 2nd series   M2 = (X+50+62+97+124)/5   M2 = 75.6   Answer = 75.6
