If `p:q=3:4` and `q:r=8:9` then `p:r` is

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

If p:q=2:3 and q:r=4,:5, then find p:q:r.

Suppose p, q, r are such that p+q=r and pqr = 30 , then what is the value of p^(3)+q^(3)-r^(3) ?

If P: Q =8.15 and Q:R =3:2 , then find P:Q:R

If P : Q = 2 : 3 and P : R = 4 : 5, then what is (P + Q) : (Q + R)?

If p,q and r are in AP,then prove that (p+2q-r)(2q+r-p)(r+p-q)=4pqr

IF P:Q=3/5:5/7, Q:R=3/4:2/5 then what is P:Q:R equal to

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
