প্রশ্ন: Half of the students of a school play football and one third of the rest play cricket. The remaining 300 students do not play either of the games. How many students are there in the school?
ব্যাখ্যা:
Fraction of students playing football = 1/2
Fraction of students playing cricket = 1/3 x 1/2 = 1/6
Fraction of students not playing either of the games = 1 - (1/2 + 1/6) = 1/3
If 1/3 of total students = 300
Then, number of total students = 300 x 3/1 = 900.
