Heya guys....
yes it would be a Composite number, since the product 7*5*3*2 is divisible by 3 so the number 7*5*3*2+3 will also be divisible by 3 hence it would be a composite number,
If you divide 7*5*3*2 by 3 the answer will simply be 7*5*2 now,
consider the multiplication 3* (7*5*2+1) the answer will be 7*5*3*2+3 hence this number has factor other than one...
In other words you can take 3 common from the given expression 7*5*3*2+3 and write it in form-
3(7*5*2+1) which proves the fact that 7*5*3*2+3 is a composite number. :)
