" If it be a sin to work hard then i am a sinner." Why do we use " be" instead of " is" in the sentence ? In mathematical problems why do we say "if x be a prime number and y be an odd number ".Why don't we say "if x is a prime number and y is an odd number."?

The uses you quote are obsolete. I haven't heard them in the 73 years I've been around. Of course you'll find them in old books.
