What values of X will be closer to the point A = -5 than the point B = 7 on the number line?
I) 0 < x < 2
II) 1 < x < 1.5
III) x < -10
A) Only I
B) Only II
C) Only III
D) Both I and III
E) Both II and III
Sol: Consider Range in option I
If x =0.9 then x is close to pt A but if x= 1.9 then pt x is close to pt B so option A and D can be ruled out
Consider range in option II. All the points in this range is close to Pt B. So option B and E is ruled out
Ans is III only or Option C only
Alternatively the question can be done by drawing a no. line. We can clearly see that that values to the left of Pt A will be closer to it than Pt B. Points to the right may or may not be close to Pt A in the given ranges in option I and II. Ans is C
