Two wheels of M.I. 3kgm^(2) and 5kgm^(2) are rotating at a rate of 600 rpm and 800 rpm respectively in opposite directions. If they are coupled so as to rotated with the same axis of rotation , the resultant speed of rotation (in rpm)

Two wheels of M.I. 3kgm^(2) and 5kgm^(2) are rotating at a rate of 600
