If `6! =2^p 3^q 5^r ` then ,`p+q +r=`

If p, q, r are in A.P the p^(2) (q + r), q^(2) (r + p), r^(2) (p+q) are in

If p:q=3:2 and q:r=6:5 then p:q:r is equal to

If P: Q = 2 : 3 , Q : R = 5 : 7 and R : S = 3 : 10 then P : S = ?

If p, q and r are perpendicular to q + r, r + p and p + q respectively and if |p + q| = 6, |q + r| = 4sqrt(3) and |r + p| = 4, then |p + q + r| is

If Q = (p + q + r )/(2) & (Q-p ) : (Q-q) : (Q -r)::17:5:8. then p :q:r = ?

If A = |{:(p,q,r),(r,p,q),(q,r,p):}|and A A ^(T) = I "then" p^(3) + q^(3) + r^(3) =
