1.	Let `A={x in R\|-9lexlt4},B={x inR\|-13ltxle5} and C={x inR\|-7lexle8}`. Then, which one of the following is correct?A. `-9in(AnnBnnC)`B. `-7in(AnnBnnC)`C. `4in(AnnBnnC)`D. `5in(AnnBnnC)`
Answer» Correct Answer - B Given sets in set builder form are : `A={x inR:-9lexlt4}` `B={x in R: -13ltx5}` `and C={x inR: -7lex le 8}` `impliesAnnBnnC={x inR: -7lex lt4}` Hence, `-7in(AnnBnnC)`
