18.By considering the given inequalities 58−≥ 1 and 1 ≤ − 4 ≤ 3, answer the followings.i. The set of values of satisfying both is :a) [3, 5) b) [3, 8] c) [1,7] d) ℎii. The number of odd integral solutions of the in-equation 1 ≤ − 4 ≤ 3 is:a) 3 b) 2 c) 5 d) 4iii. Number of non zero integral solution of 58−≥ 1 is:a) 5 b) 4 c) 3 d)2iv. By taking all non zero integral solutions of the above in-equations (satisfying both), the total number of 2 digit numbers (with repetition of digits) that can be formed is :a) 27 b) 6 c) 8 d) 9v. The sum of all 4 digit numbers formed by all odd integral solutions of the in-equation 1 ≤ − 4 ≤ 3 is: a) 96960 b) 106656 c) 105696 d) 97056 |
