If x is a natural number and 20x≤100 then find solution set of x.(a)

1.	If x is a natural number and 20x≤100 then find solution set of x.(a) {0,1,2,3,4,5}(b) {1,2,3,4,5}(c) {1,2,3,4}(d) {0,1,2,3,4}The question was posed to me during an interview.The origin of the question is Algebraic Solutions of Linear Inequalities in One Variable and their Graphical Representation topic in section Linear Inequalities of Mathematics – Class 11
Answer» The correct answer is (b) {1,2,3,4,5} The EXPLANATION: 20x≤100 Dividing by 20 on both SIDES, x ≤ (100/20) => x≤5 Since x is a NATURAL NUMBER so x = 1,2,3,4,5.
