(a) P, Q and R are three quantities such that P varies directly as the square of Q and inversely as the square root of R.
(i) Given that P = 12 when Q = 24 and R = 36, find P when Q = 27 and R = 121.
(ii) If Q increases by 10% and R decreases by 25%, find the percentage increase in P.
(b) If Q is inversely proportional to the square root of P and P = 4 when Q = 3.
Calculate the value of P when Q = 8.
