Statement 1
Total time; \(4\cdot 60= 240\) mins
so words typed by each
A- \(240\cdot 40\)
B- \(240\cdot 50\)
C- \(240\cdot 60\)
We can find total words and \(\%\); sufficient. \(\Large{\color{green}\checkmark}\)

Statement 2
Fastest \(150\%\) of slowest
no rates given. Insufficient. \(\Large{\color{red}\chi}\)

Therefore, A
