1.	If `A={x:x in N and xlt6(1)/(4)}` and `B={x: x in N and x^(2)le5)` the number of subsets of set `Axx(AcapB)` which contains exactly 3 elements isA. 126B. 280C. 220D. 144
Answer» Correct Answer - C `thereforea=[1,2,3,4,5,6},B={1,2}` `thereforeAcapB={1,2}` `thereforen(Axx(AcapB))=12` `therefore` required `=.^(12)C_(3)=220`
