JEE Main 2022 — Basic of Mathematics Question with Solution

JEE Main 2022 (25 Jun Shift 2)

Question

Let A=x∈R:x+1<2 and B=x∈R:x-1≥2. Then which one the following statements is NOT true?

Choose an option

Show full solutionCorrect option: B
Correct answer
BB-A=R--3,1

Step-by-step explanation

Given,

A=x∈R:x+1<2

⇒A=-3,1

Now, B=x∈R:x-1≥2

⇒B=(-∞,-1]∪[3,∞)

Now, B-A=(-∞,-3]∪[3,∞)

⇒B-A=R--3,3

So, option B is not true.
