Here, n(U) = 50, no(M) = 10 , no(S) = 15, n(MUS)' = 10 Vann-diagram: From the diagram, 50 = 10 + x + 15 + 10 Find x. Then, n(M) = 10 + x n(S) = 15 + x Finally, find n(M) / .....
Let, x be the total no.of students. Then, n(Ar) = 9x n(Al) = 8x, n(Ar∩Al) = 25% of x = x/4 no(Ar) = 20% of x = x/5 n(Ar U Al)' = 80 Now, n(ArUAl) = n(Ar) + n(Al) - n(Al ∩ Ar) or, x - 80 .....
Here, n(U) = 100% n(B) = 45% , n(C) = 40%, n(B∩C) = 30% n(BUC)' = 360 We know, n(BUC) = n(B) + n(C) - n(B∩C) = 40 + 45 - 30 = 55% Again, n(BUC) .....
Here, n(U) = 100, n(S) = 80, n(M) = 71 n(MUS)' = 7 + 10 = 17 Now, let x be the no.of students who passed in both. From the diagram, 100 = 71-x + x + 80 - x + 10 Find .....
