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 _________.
