If the mean of numbers 28, x, 50, 78 and 104 is 62, what is the mean of 48, 62, 98, 124 and x? Choose the correct choice from the following answers
A) 76.5  B) 58  C) 39.8  D) 90.3  E) 66.67
Mean = (Sum of all no. in series)/(no. in series)   M1 = 62 = (X+28+50+78+104)/(5)   62 x 5 = 260 + X   X = 50   Therefore mean of 2nd series   M2 = (X+48+62+98+124)/5   M2 = 76.5   76.5nswer = 76.5
