X are values less than 7, thus, X = {..., -1, 0, 1, 2, 3, 4, 5, 6}

Y = factors of 24 = {1, 2, 3, 4, 6, 8, 12, 24}

But since the X and Y are subsets of U, and U = real numbers from 1 to 10, X and Y must have values between 1 and 10 only.

Thus, X = {1, 2, 3, 4, 5, 6}

Y = {1, 2, 3, 4, 6, 8}

Hence, X n Y = {1, 2, 3, 4, 6}

Ans B
