Question

If x is a whole number and 10x≤50 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}

I had been asked this question by my school teacher while I was bunking the class.

Answer 1

Right choice is (a) {0,1,2,3,4,5}

Explanation: 10x≤50

Dividing by 10 on both sides, x ≤ (50/10) => x≤5

Since x is a whole number so x = 0,1,2,3,4,5.
