20. If two sides of a rhombus ABCD are parallel to the lines y=x+2 and y=7x +3. If the diagonal of the rhombus intersect at the point (1,2) and the vertex A lies on y- ihen the possible coordinates of A is equal to 3)(0.1) (NUMERICAL VALUE TYPE) This section contairs 5 questions. Each quesion s nunerkcal value. For each question, enker the orrect numerical value (in decimal notation, truncated/rounded-off to second decimal place. Jeg 625. 7.00, -0.33, -30, 3027, -127 30) Marking scheme: +4 for correct answer, O if not allempted and 0 in all olher cases. The absolute value of the sum of the abscissas of ail the points on the x+y=4 that lie at a unit distance from the line 4x+3y -10=0 is 22. If the coordinates of the orthocentre of the triangle formed by the lines y=0,37x - 36y + 37 x 36 = 0 and 64x - 63y +64 x 63=0 is (a.b) then a-b-4535 is 23. The length of the largest altitude of the triangle formed hy the lines 7x - 2y + 10-0,7x + 2y-10-0 and y+2-0 is 24. The sum of algebraic distances from the points (n.n') where n=1,2,3 2013, to a straight line is zero and if such a line always 1007 passes through the point (a.p) an = abed Then b+d is (abcd is 4 3 digited number) 25. If the equations or ne diagonal of the parallelogram formed by the lines 2x - y+7-0: 2x -y-3-0. 3x + 2y -5-0 and 3x + 2y + 4-0 are ax + by -5-0 and px + qy +1=0 the value of a+b+p+q is 20.
