Question

The largest six digit telephone number that can be formed by using digits $$5,3,4,7,0,8$$ only once is $$875403$$.

Answer 1

Correct option is B. False

$$\textbf{Reason:}$$ If we arrange the above digits in descending order $$8 > 7 > 5 > 4 > 3 > 0$$, we get the largest phone number. Hence, the largest six digit telephone number that can be formed is $$\textbf{875430}$$ and not $$\textbf{875403}$$ as $$\textbf{875430 > 875403}$$.

$$\therefore\ \textbf{The given statement is False}.$$
