Question

If P = {4, 5, 6, 7, 8, 9}, Q = {2, 3, 4}, R = {4, 5, 8}, then which of the following statements are correct?

• A. $P\subset Q$
• B. $R\subset P$
• C. $Q\subset R$
• D. None of the above

Answer 1

The correct option is B $R\subset P$

Given :
P = {4, 5, 6, 7, 8, 9}
Q = {2, 3, 4}
R = {4, 5, 8}
All the elements of R are elements of P.
$\Rightarrow R\subset P$
