Moment of Inertia (M.I.) of four bodies having same mass '\( M \)' and radius '\( 2R \)' are as follows:
\( I_{1} \) = M.I. of solid sphere about its diameter
\( I_{2} \) = M.I. of solid cylinder about its axis
\( I_{3} \) = M.I. of solid circular disc about its diameter
\( I_{4} \) = M.I. of thin circular ring about its diameter
If \( 2 ( I_{2} + I_{3} ) + I_{4} = x \cdot I_{1} \) then the value of \( x \) will be __________.
