A solid sphere and a spherical shell roll down an incline from rest from same height. The ratio of times taken by them is

When a uniform solid sphere and a disc of the same mass and of the same radius roll down an inclined smooth plane from rest to the same distance, then ratio of the time taken by them is

A thin circular ring first slips down a smooth incline then rolls down a rough incline of identical geometry from same height. Ratio of time taken in the two motion is :
