Question

X = the sets of all letters in the word “DELHI” and
Y = the sets of all letters in the word “INDIA”.
Find X ∪ Y.

• A. {D, E, L, H, I, I, N, D, I, A}
• B. {I, H, A, N}
• C. {D, E, L, H, I, N, A}
• D. {E, D, H, I, N}

Answer 1

The correct option is C {D, E, L, H, I, N, A}

X = {D, E, L, H, I}
Y = {I, N, D, A}
$X\cup Y$ = {D, E, L, H, I, N, A}

So, option c is correct.
