If `(1)/(p+q)=r and pne-q`. What is p in terms of r and q?

If p=(sqrt(q)+z)/(r^(2)+z) , what is the value of z in terms of p, q, and r ?

If (p ^(2) + q ^(2)) // (r ^(2) + s ^(2)) = (pq) //(rs), then what is the value of (p-q)/(p+q) in terms of r and s ?

If the prth term of an A.P. is q and qth term is p, then rth term is (A) q-p+r (B) p-q+r (C) p+q+r (D) p+q-r

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 P is the husband of Q and R is the mother of S and Q, what is R to P?

If the p^(th) term if an A.P. is q and the q^(th) term of an A.P is p then the r^(th) term is
