Que-1: Which of the following is not a linear inequation?

Solution- (d) 6x+13 < 4/x – 3
Reason: as x is in denominator

Solution- (c) (7x/3)-9 ≤ 5+(4x/7)
Reason: Others are either in squire form or x is in denominator

(a) ax+b > c (b) (a/x)+b ≥ c (c) ax+b ≤ c (d) ax²+b < c
Solution- (d) ax²+b < c
Reason: variable is in squire form
Que-4: Which of the following is reducible to a linear inequation?
(a) 7-x² ≤ 5x+3 (b) (3/x)-8 > 4 (c) 4-(2/x) ≥ (1/x²)-6 (d) 11-x ≤ 5x²+6

Reason:
Que-5: Which of the following is not reducible to a linear inequation?
(a) 3-(7/x) < 5 (b) 8+(3/x) ≥ (5/x)-4 (c) (6/x)-8 > (4/x)+3x (d) 3/(x-1)-7 < 9
Solution- (c) (6/x)-8 > (4/x)+3x
Reason: on solving (c) it becomes quadratic form
Que-6: Which of the following is not true for the linear inequations?
(a) Adding the same number to each side of an inequation does not change the inequality.
(b) Multiplying each side of an inequation by the same positive number reverses the inequality.
(c) Multiplying each side of an inequation by the same negative number reverses the inequality.
(d) Dividing each side of an inequation by the same positive number does not change the inequality.
Solution- not true option is (b) Multiplying each side of an inequation by the same positive number reverses the inequality.
Reason: Multiplying / dividing each side of an inequation by the same positive number No change in the inequality sign. Only change if Mul / Div. by negative number
Que-7: Which of the following is not true?
(a) p>q ⇔ q>p (b) p<q ⇔ q>p (c) p≥q ⇔ q≤p (d) p≤q ⇔ q≥p
Solution- (a) p>q ⇔ q>p
Reason: in LHS P is greater while in RHS P is smaller Hence it is not possible
Que-8: Which of the following is the solution set of x≤7, when the replacement set is the set of natural numbers?
(a) {1,2,3,4,5,6,7} (b) {0,1,2,3,4,5,6,7} (c) {1,2,3,4,5,6} (d) {0,1,2,3,4,5,6}
Solution- (a) {1,2,3,4,5,6,7}
Reason: because sign ≤ indicate not only smaller but also equal hence 7 is also added in solution set of (a) while (b) contain 0 which is not natural number set
Que-9: Which of the following is the solution set of x<0, when the replacement set is the set of whole number?
(a) {0} (b) {…….,-3,-2,-1} (c) {…….,-3,-2,-1,0,} (d) Null set
Solution- (d) Null set
Reason: as x is whole number so the least value is 0 and there is no number less than 0 in whole number
Que-10: Which of the following is the solution set of x≤3, when the replacement set is the set of integers?
(a) {0,1,2,3} (b) {…,-2,-1,0,1,2} (c) {…,-2,-1,0,1,2,3} (d) {…,-2,-1,1,2,3}
Solution- (c) {….,-2,-1,0,1,2,3}
Reason: as x is integer so all negative number, zero and up to 3 positive number may be solution set
Que-11: Which of the following statements is not true? (r is a positive integer)

Solution- (b) If p≥q, then -pr ≥-qr
Reason: on multiplying both side negative number sign must be reverse here – r is multiplying both side without sign change hence it is not true
Que-12: Which of the following statements is true?(r is a positive integer)
(a) If p≥q, then (-p/r) ≤ (-q/r) (b) If p≤q, then pr ≥ qr (c) If p>q, then -pr > -qr (d) If p<q, then p-r < q-r
Solution- (a) If p≥q, then (-p/r) ≤ (-q/r)
Reason: on multiplying both side negative number sign must be reverse
