Question

Assume the first two statements are true. In the final statement: 1) True 2) false, or 3) uncertain based on the information provided? Derek is older than Emily. Frank is younger then Emily. Derek is younger than frank.

Answer 1

Answer:

The statement 'Derek is younger than frank' is false

Explanation:

Given:

Derek is older than Emily.

Frank is younger than Emily.

are both true statements

To Find:
Derek is younger than Frank is true or false

Solution:
If Derek(D) is older than Emily(E) then D>E

If Frank(F) is younger than Emily(E) then F<E

This creates a chain of D>E>F

As Derek is older than Emily this makes Frank younger than both Emily and Derek.

However, the statement mentions that Derek is younger than Frank but the equation proves that,

Derek is older than Frank.

This, concludes that statement three is False.
