alleryA team won 10 matches and its win percentage was 40. How many matches did it play in all?
A20
B30
C24
D25
Answer & Solution
Correct answer: D. 25
1. Let the number of matches played be x.
2. 40 per cent of x = 10 wins, so (40/100) x = 10.
3. x = (10 x 100) / 40 = 25.
4. Check: 40 per cent of 25 = 10 wins and 15 losses.
