Question
Contrapositive of the statement “If two numbers are not equal, then their squares are not equal.” is :
Select the correct option:
A
If the squares of two numbers are equal, then the numbers are equal
B
If the squares of two numbers are not equal, then the numbers are equal
C
If the squares of two numbers are equal, then the numbers are not equal
D
If the squares of two numbers are not equal, then the numbers are not equal
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Contrapositive of "If A then B" is "If $\sim B$ then $\sim A$ " Hence contrapositive of "If two numbers are not equal, then their squares are not equal" is "If squares of two numbers are equal, then the two numbers are equal".
