Question

In a class, 8% of total students are interested in Football. Four-fifth of total students are interested in Cricket. 10% of total students are interested in Basketball and remaining 20 students are not interested in any games. How many students are there in the class?

Answer 1

Answer:

1000 students

Step-by-step explanation:

The trick is to identify the percentages of students of all categories.

Four fifths implies 4/5 which is 80% (Cricket).

8% (Football)

10% (Basketball)

Total until now is 80%+10%+8% = 98%

So, remaining will be 2% (not interested in any sport) = 20 students.

Now a simple ratio method will suffice. If 2% corresponds to 20 students, 100% will correspond to X students.

Solving for it will yield answer 1000 students.
