Question

The high school baseball team has won four of its last five games under Mark's leadership. How many games would the team have to play in order to win 20 games if they keep winning at the same rate?

• A. 16
• B. 25
• C. 24
• D. 20

Answer 1

The correct option is B 25

Ratio of matches won by Mark's team to the total number of matches played = 4 : 5
Let the team plays $x$ matches in order to win 20 matches.
Winning rate remains the same
$\Rightarrow 4:5::20:x$
$\Rightarrow \frac{4}{5}=\frac{20}{x}$
By cross-multiplication,
$4\times x=5\times 20$
$\Rightarrow x=25$
$\therefore$ In 25 games they will be able to get 20 wins.
