Question

If A = {x: x is a letter of the word SET} and B = {x: x is a letter of the word SETTEE}, then A and B are ___.

• A. null sets
• B. singleton sets
• C. equivalent sets
• D. equal sets

Answer 1

The correct option is D

equal sets

A = {x: x is a letter of the word SET}

A = {s,e,t}

B = {x: x is a letter of the word SETTEE}

B ={s,e,t}

As A and B have the same elements, A = B

$\Rightarrow$ A and B are equal sets

Hence (D)
