Here are some possibilities:
* If "mutiyar" refers to a young woman, then the opposite could be "budda" (old man) or "budhi" (old woman).
* If "mutiyar" refers to a young, unmarried woman, then the opposite could be "shaadi shuda" (married).
* If "mutiyar" refers to a beautiful, young woman, then the opposite could be "badsurat" (ugly).
To give you a more precise answer, please provide me with the context in which you are using the word "mutiyar".
