If ""^(n)C_(a)= ""^(n)C_(b) ' then find n.

The mean of first n odd natural number is (a) (n+1)/2 (b) n/2 (c) n (d) n^2

The sum of first n odd natural numbers is 2n-1 (b) 2n+1 (c) n^2 (d) n^2-1

If n(A) = 6 and n(B) = 8 and n(A nn B) = 4 , then find n(A Delta B) . The following are the step involved in solving the above problem . Arrange them in sequnential order. (a) n (A uu B) = n(A) + n(B) - n(A nn B) (b) n(A uu B) = 10 (c ) n(A uu B) =6+8-4 (d) n(A Delta B) = 10-4= 6 (e) n(A Delta B) = n(A uu B) - n(A nn B) .

If n (A) = 65, n(B) = 32 and n (A nn B) = 14, then n (A Delta B) equals

If A and B are two sets that n(A-B)=14+x in n(A)=n(B) and n(B-A)=3x and also n(A nn B) =x .Then x is equal to a."8," b."7," c."9," d.None of these

A ,\ B\ a n d\ C can reap a field in 15 3/4 days : B ,\ C\ a n d\ D in 14 days: C ,\ D\ a n d\ A in 18 days: D ,\ A\ a n d\ B in 21 days. In what time can A ,\ B ,\ C\ a n d\ D together reap it?

If A and B are two sets such that n(A) =8, n(B)=11 and n(A cup B) =14 then find n(Acap B) .
