If `x` is prime, `y` is a composite number such that `x+y=240` and their LCM is 4199. Find `x\ a n d\ ydot`

If m is prime,n is a composite number and m+n=240 also their LCM is 4199. Find m and n.

If x ={Non-prime numbers } and Y= {Non composite numbers },then n(x cap Y) _______.

If x, y, z are natural numbers such that LCM(x, y) =2744, LCM(y, z) = 1372 and LCM(z, x) = 2744, then the number of triplets of (x, y, z) is 'n' where sum of the digits of n is

In Fig.79, D E B Cdot Find the value of x\ a n d\ ydot

Consider the following statements I. If x and y are composite integers, so x + y is also composite. II. If x and y are composite integers and x gt y, then x - y is also a composite integer. III. If x and y are composite integers, so also is xy. Of the above, the correct statement is/are
