Question

29. Out of 30 students in a class, 6 like football, 12 like cricket, and remaining like tennis. Find the ratio of the number of students liking football to the number of students liking tennis. *

Answer 1

GivEn that:

• Total students are 30
• Number of students like football = 6
• Number of students like cricket = 12
• And, remaining like tennis

To finD:

• Ratio of number of students like football and students like tennis.

Answer :

Required ratio is 1/2 or 1:2

Explanation:

Here, we have are given that total students are 30 in which 6 like football and 12 like cricket.

Therefore, number of students like tennis =

Number of students like tennis = Total students -(students like football + students like cricket)

=> Number of students like tennis = 30 -(6 + 12 )

=> Number of students like tennis = 30 - 18

=> Number of students like tennis = 12

∴ Number of students like tennis = 12

Now, asked that what is the ratio of students which like football to the students like tennis.

Ratio of students like football to the tennis =

Ratio of students like football to the tennis = $\large{\tt{\frac{Students ~like~ football }{students ~like~ tennis}}}$

=> $\large{\tt{\frac{Students ~like~ football }{students~ like~ tennis} = \frac{6}{12}}}$

=> $\large{\tt{\dfrac{1}{2}}}$

∴ Ratio of students like football to the tennis =

1/2 or 1:2

Answer 2

Given:

Number of students who like football = 6

Number of students who like cricket = 12

Number of students who like tennis = 30 – 6 – 12 = 12

Solution:

(a) Ratio of number of students like football to the number of students like tennis

= 6 / 12

= 1 / 2

= 1:2 Ans

(b) Ratio of number of students liking cricket to total number of

= 12 / 30

= 2 / 5

= 2:5 Ans
