Actually, the intertia depends on the weight of the object. The more the weight, the more will be the inetia, so it depends who weighs more. but it is common sense that man will weigh more, so the man will have more inertia.

No, inertia is directly proportional to mass of the body, not to the weight. The more will be the mass, the more will be the inertia.
