We know that, A universal set is the set of elements from which elements may be chosen to form sets for a particular discussion. Consider a set 0 , 3 , 6 , 9 , 12 , 15 , We can see that, the elements of above set belongs to multiples of 3 . Hence, the universal set of the set can be a set of multiples of 3 , i.e, E = multiples of 3 . Now, consider a set 1 , 3 , 5 , 7 , 9 , 11 , We can see that, the elements of above set belongs to odd numbers. Hence, the universal set of the set can be a set of odd numbers, i.e, A = odd numbers . Now, consider a set pine , oak , deodar , We can see that, the elements of above set belongs to names of trees. Hence, the universal set of the set can be a set of trees, i.e, D = trees . Now, consider a set Himalayas , Alps , Andes , We can see that, the elements of above set belongs to names of mountains. Hence, the universal set of the set can be a set of mountains, i.e, B = mountains . Now, consider a set 1 3 , 1 5 , 1 9 , 1 4 , 1 11 , We can see that, the elements of above set belongs to fractional numbers. Hence, the universal set of the set can be a set of fractional numbers, i.e, C = fractional numbers . Thus, the required answer is ( i ) 0 , 3 , 6 , 9 , 12 , 15 E = multiples of 3 ( ii ) 1 , 3 , 5 , 7 , 9 , 11 A = odd numbers ( iii ) pine , oak , deodar D = trees ( iv ) Himalayas , Alps , Andes B = mountains ( v ) 1 3 , 1 5 , 1 9 , 1 4 , 1 11 F = fractional numbers
