3. Suppose set \( A \) consists of first 250 natural numbers that are multiples of 3 and set \( B \) consists of first 200 even natural numbers. How many elements does \( A \cup B \) have? (a) 324 (b) 364 (c) 384 (d) 400

Given: n(A)=250              n(B)=200 A={3,6,9,12,.......750} B=2,4,6,8,10.......400} Therefore,A⋂B={6,12,18....396)                   =>n(A⋂B)=396/6=66   n(A∪B)=n(A)+n(B)-n(A⋂B)               =250+200-66              ...

Mean of three consecutive even numbers is 16. The numbers are 

Correct option is (D) 14, 16, 18 Let three consecutive even numbers are x - 2, x & x+2. \(\therefore\) Their mean \(=\frac{(x-2)+x+(x+2)}3\) \(=\frac{3x}3\) = x But given that mean of three consecutive even numbers is 16. \(\therefore\) x = 16 Thus,...
