6. In a school 95 boys appeared for a physical test for selection in NCC and Boys Scouts. Among them, 21 boys got selected in NCC as well as Boy Scouts, 44 boys were not selected in Boy Scouts, and 20 boys were not selected only in Boy Scouts draw Venn diagrams and find:

(i) how many boys did not get selected in NCC and Boy Scouts?
(ii) how many boys did not get selected only in NCC?
(iii) how many boys got selected in NCC?
(iv) how many boys got selected in Boy Scouts? 
(v) how many boys got selected in NCC but not Boy Scouts? 

(Hint: Solving the question will be easier if you begin with a Venn diagram for boys who did not get selected).
