7×6×3×5+5 is a not composite no because when we solve it comes 635 and it odd no and 112 is even no
it 112.

simple
going by basic definition composite no. has more than 2 factors (including 1 and the no. itself)
so, 3*5*7+7 = 7*(3*5 + 1) (7 is a factor)
and 7*6*3*5+5 = 5*(7*6*3 + 1) (5 is a factor)
so both are composite.
I guess something is wrong with your question
