1. 2. 3. If a, b are odd integers then number of integral root, of equation x10 + ax + b = 0 is equal to If the number of distinct positive rational numbers P smaller than 1, where p, q = {1, 2, 3 ....., 6} is k then k is If two distinct chords of a parabola y = 4ax passing through (a, 2a) are bisected on the line x + y = 1, then the sum of integral values of the length of possible latus rectums is equal to sec 2-5x 4. If the value of Lim sin is e^ then 'A' is 2-3x 5. If a, b, c, such that ax(axc)+3b=0, if 0 is the angle between a and c, then cos 0 is equal to
