Answer 2

To Find :

• (i) B - C
• (ii) B - D
• (iii) C - D
• (iv) D - B

Solution :

• A = {3 , 6 ,9 ,12 ,15 ,18 ,21}
• B = {4 ,8 ,12 ,16 ,20}
• C = {2 ,4 ,6 ,8, 10 ,12 ,14, 16}
• D = {5, 10 ,15 ,20}

(i) B - C

• B = {4 ,8 ,12 ,16 ,20}
• C = {2 ,4 ,6 ,8, 10 ,12 ,14, 16}

• B - C = {20}

(ii) B - D

• B = {4 ,8 ,12 ,16 ,20}
• D = {5, 10 ,15 ,20}

• B - D = {4 ,8 ,12, 16}

(iii) C - D

• C = {2 ,4 ,6 ,8, 10 ,12 ,14, 16}
• D = {5, 10 ,15 ,20}

• C - D = {2 ,4 ,6 ,8 ,12, 14, 16}

(iv) D - B

• D = {5, 10 ,15 ,20}
• B = {4 ,8 ,12 ,16 ,20}

• D - B = {5 ,10 ,15 }
