(vi) D – A (vii) B – C (viii) B – D (ix) C – B (x) D – B

Answer 1

hey dear
here is your answer ✌ ✌

============

(i) A-B = {3,6,9,15,18,21}
(ii) A-C = {3,9,15,18,21}
(iii) A-D = {3,6,9,12,18.21}
(iv) B-A ={4,8,16,20}
(v) C-A = {2,4,8,10,14,16}
(vi) D-A = {5,10,20}
(vii) B-C = {20}
(viii) B-D = {4,8,12,16}
(ix) C-B = {2,6,10,14}
(x) D-B = {5,10,15}
