The value of [0.9-{2.3-3.2-(7.1 - 5.4 - 3.5)}] is: [0.9-{2.3-3.2-(7.1 - 5.4 - 3.5)}] का मान है :

A= {1, 2, 3, 4, 5, 6}, B= {1, 2, 3, 7, 8, 10}, C= {1, 2, 5, 9, 10}, U= {1, 2,3, 4, 5, 6, 7, 8, 9, 10, 11} Show these sets in Venn diagram.

The average of a, b and c is 9. The average of b and c is 10. What is the value of a? a, b तथा c का औसत 9 है | b तथा c का औसत 10 है | a का मान कितना है ?

If A = {1, 3, 9, 10, 21), B= {4, 6, 8, 10} and C = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, then the value of A cap (B cap C) is
