A school organised a picnic. In a group of 100 students, 55% enjoy rides, 40% play football, 15% sit in a park, then which conclusion(s) can not be drawn from the above data. a) 20% play football as well as enjoy rides. b) Neither a single student play football nor enjoy rides. Select the correct options ∶  Correct Answer Neither a nor b

Given∶

55% enjoy rides.

40% play football.

15% sits in  park.

Formula Used∶

Basics of percentage and simplification.

Calculation∶

Total students = 100

Let the no. of students who enjoy rides as well as play football be x.

Number of students enjoy rides = 55% of 100 = 55

Number of students play football match = 40% of 100 = 40

Number of students sits in a park = 15% of 100 = 15

Total no. of students in the class = No. of students who enjoy rides + No. of students play football + No. of students who sits in a park - No. of students who enjoy rides as well as play football

⇒

 100 = 55 + 40 + 15 - x

⇒

 x = 110 - 100

⇒ 

x = 10

So, statement a and b both are wrong.

∴ 10 students play football as well as enjoy rides. Option 4 is correct.
