Question

If A = {x: x = 4 q + 3, q N, 5 < q < 6} , B = {x: x N and 10< x<50} and C = { x : x is smaller than 50 and multiple of 3, x N }. then find A × B × C.

Answer 1

Answer:

(i) 43∈ Q (ii) -2∉N (iii) P = {p | p is an odd number} ... { x | x 2 = 0} ( iii ) C = { x | 5 x - 2 = 0, x∈N} ... (i) A = {x | x < 10, x is a natural number} = {1, 2, 3, 4, 5, 6, 7, 8, 9}
