In a school of 600 students, 40% play sports. Of those who play sports, 25% play cricket. What percentage of all students play cricket?
A$65\%$
B$15\%$
C$10\%$
D$40\%$
Answer & Solution
Correct answer: C. $10\%$
40% of 25% = 0.40 × 0.25 = 0.10 = 10% of all students. Adding (65%) or subtracting (15%) the percentages are the classic CAT traps.
