You will not be allowed to write during the first 15 minutes. This time is to be spent in reading the question paper. The time given at the head of this paper is the time allowed for writing the answers. Attempt all questions from Section A and any four questions from Section B. All working, including rough work, must be clearly shown and must be done on the same sheet as the rest of the answer. Omission of essential working will result in the loss of marks. The intended marks for questions or parts of questions are given in brackets [ ]. Mathematical tables are provided. Question 1: A {x :11x 5 7 x 3, x R} and B {x :18x 9 12 x 15, x R}. Find A B and (a) Given: represent it on a number line. (b) There are three containers of equal capacity and all are completely filled with mixtures of acid and water in different ratios. The ratio of acid to water in the first container is 2:3, in the second container the ratio is 3:7 and in the third container it is 4:11. If the mixtures of all the three containers are mixed together, what will be the ratio of acid to water in it? 17 7 1 3 (c) B and C are two matrices such that B and C , find the matrix A so that 4 8 2 0 BA C .
