Moment of Inertia (M.I.) of four bodies having same mass 'M' and radius '2R' are as follows:

I1 = M.I. of solid sphere about its diameter

I2 = M.I. of solid cylinder about its axis

I3 = M.I. of solid circular disc about its diameter

I4 = M.I. of thin circular ring about its diameter

If 2(I2 + I3) + I4 = x . I1, then the value of x will be __________.
