Here, no(A) = 12, no(B) = 15, n(A U B)' = 11 and n(U) = 45. Now, (i) n(A U B) = n(U) - n(AUB) = 45 - 11 = 34. (ii) n(A ⋂ B) = n(AUB) - no(A) - no(B) = 34 - 12 - 15 = 7. (iii) n(A) = no(A) .....
We have given, n(A) = 65, n(B) = 80 and A⊂B, Now, (i) n(A ∪ B) = n(B) = 80 [ since,A⊂B.] (ii) n(A ∩ B) = n(A) = 65 [ since,A⊂B.] (iii) n(A - B) = 0 .....
Here, n(U) = 90, n(P) = 45, n(Q) = 35 and n(P U Q)' = 15, Venn-diagram; Now, (i) n(P U Q) = n(U) - n(PUQ)' = 90 - 15 = 75 (ii) n(P ⋂ Q) = n(P) + n(Q) - n(PUQ) = 45 + 35 - 75 = 5 (iii)no(P) = n(P) .....
Given, n(U) = 60 n(A) = 30 n(B) = 40 n(A∪B) = 55 n(A∩B) = ? n(A∩B)' = ? no(A) = ? no(B) = ? Now, n(A∪B) = n(A) + n(B) - n(A∩B) or, 55 = 30 + 40 - n(A∩B) ∴ n(A∩B) = 70 - 55 = .....
We have given, n(U) = 50, n(A) = 25, n(B) = 27 and n(A⋂B) = 10. Now, (i) n(A U B) = n(A) + n(B) - n(A⋂B) = 25 + 27 - 10 = 42 (ii) n(A U B)' = n(U) - n(AUB) = 50 - 42 = 8 (iii) n(only A) = n(A) - n(A⋂B) = 25 - 10 = .....
From the Venn diagram, no(N) = 75 - x n(N ∩ E) = x no(E) = 60 - x Now, n(N ∪ E) = no(N) + n(N ∩ E) + no(E) or, 110 = 75 - x + x + 60 - x On solving this we get x = 25 ∴ no(N) = 75 - .....
Here, From the venn-diagram, (i) n(T∪M) = 15 + 20 + 18 = 53 (ii) n(T∩M) = 20 (iv) n0(T) = 15 (v) n0(M) = 18 (vi) n(U) = 15 + 20 + 18 + 5 = .....
Here, SP with VAT = Rs. 20064 or, SP + VAT% of SP = Rs. 20064 or, SP + 10% ⨉ SP = Rs. 20064 or, 1.1SP = Rs. 20064 So, SP = Rs. 20064/ 1.1 = Rs. 18240 Now, SP = MP - D% of MP or, 18240= MP - 5% ⨉ MP or, 18240= .....
Here, SP with VAT = Rs. 9153 or, SP + VAT% of SP = Rs. 9153 or, SP + 13% ⨉ SP = Rs. 9153 or, 1.13SP = Rs. 9153 So, SP = Rs. 9153 / 1.13 = Rs. 8100 Now, SP = MP - D% of MP or, 8100 = MP - 10% ⨉ MP or, 8100 = .....
