If `A={x: |x|lt2},B={x: |x-5|le2}`,
`C={x: |x|gtx}andD={x: |x|ltx}`
The number of integral values in `AnnD` is

A

2

B

4

C

6

D

0

Text Solution

Verified by Experts

The correct Answer is:
D
`A={x: |x|lt2}={x:-2ltxlt2}=(-2,2)`
`B={x: |x-5|le2}={x:-2lex-5le2}`
`={x:3lexle7}=[3,7]`
`C={x: |x|gtx}={x:xlt0}=(-oo,0)`
and `D={x: |x|ltx}=phi`
`AnnD=(-2,2)nnphi=phi`
`therefore` Number of integral values in `AnnD` is 0.
