Q11 :  just place the numbers as they tell u the rest keep it in E

A = prime numbers  means  ( 41, 43, 47 )
B = Odd numbers means ( 45, 49 )
E = the numbers which are left (40, 42, 44,46,48 )

b) n (BnA')
 first fine BnA  = ( 45, 49, 41 ,43, 47 )  since prime numbers are odd too the will be same
now remove A from it  =  ( 45 , 49 )   these 2 are left

they want the number so answer is = 2

hope u understand that .. sry dono the rest yet
