can a body having larger mass be hotter than another of smaller mass. if they are at same temperature .explain

No, of course.

Explanation:

By definition, this is not possible. You can maybe feel the larger mass body hotter, but it only produces the heat better than the smaller mass body.

You may think the large body produces more heat because the surface of the body is bigger. But, as the question says, both bodies have the same temperature, so it's impossible that one is hotter than the other.
