Answer 2

Given:-

• Total number of students in a school = 1800
• Number of students opted basketball = 750
• number of students opted cricket = 800
• Given, remaining students opted table tennis.

Solution:-

(a) Ratio of students who opted basketball to the number of students who opted table tennis.

Answer:

Number of students opted table tennis

Let the number of students opted table tennis be x

➦ 750 + 500 + x = 1800

➦ 1550 + x = 1800

➦ x = 1800 - 1550

➦ x = 250

Therefore, Number of students opted table tennis are 250

Now, ratio = Basketball : Tennis

➦ 750 : 250 ( Cancelling 0s )

➦ 75 : 25

➦ 3 : 1

(b) Ratio of students who opted cricket to the number of students opted basketball

Answer:

Ratio = Cricket : Basketball

➦ 800 : 750 ( Cancelling 0s )

➦ 16 : 15

(c) Ratio of students who opted basketball to the total number of students.

Answer:

Ratio = Basketball : Total number of students

➦ 750 : 1800 ( cancelling 0s )

➦ 25 : 60

➦ 5 : 12

Required Answer:

• (a) Ratio of students who opted basketball to the number of students who opted table tennis is 3 : 1
• (b) Ratio of students who opted cricket to the number of students opted basketball is 16 : 15
• (c) Ratio of students who opted basketball to the total number of students is 5 : 12
