Total number of students = 1800
Number of students opted basketball = 750
Number of students opted cricket = 800
Therefore, number of students opted tennis = 1800 – (750 + 800) = 250
(a) Ratio of students opted basketball to that of opted table tennis = \(\frac{750}{250}\)
\(=\frac{ 3}{1}\)
\(= 3:1\)
(b) Ratio of students opted cricket to students opted basketball =\(\frac{ 800}{750}\)
\(= \frac{16}{15}\)
\(= 16:15\)
(c) Ratio of students opted basketball to total no. of students = \(\frac{750}{1800}\)
\(= \frac{5}{12}\)
\(= 5:12\)
Number of students opted basketball = 750
Number of students opted cricket = 800
Therefore, number of students opted tennis = 1800 – (750 + 800) = 250
(a) Ratio of students opted basketball to that of opted table tennis = \(\frac{750}{250}\)
\(=\frac{ 3}{1}\)
\(= 3:1\)
(b) Ratio of students opted cricket to students opted basketball =\(\frac{ 800}{750}\)
\(= \frac{16}{15}\)
\(= 16:15\)
(c) Ratio of students opted basketball to total no. of students = \(\frac{750}{1800}\)
\(= \frac{5}{12}\)
\(= 5:12\)

Approach Solution -2
Total number of students: 1800
Number of students who chose basketball: 750
Number of students who chose cricket: 800
Number of students who chose table tennis: Total number of students - Number of basketball students - Number of cricket students
\(= 1800 - 750 - 800\)
\(= 250\)
(a) Ratio of basketball students to table tennis students:
= \(\frac{\text{Number of basketball students}}{\text{Number of table tennis students}}\)
= \(\frac{750 }{ 250}\)
=\(\frac{ 3 }{ 1}\)
So, the ratio of basketball students to table tennis students is 3:1.
(b) Ratio of cricket students to basketball students:
= \(\frac{\text{Number of cricket students}}{\text{Number of basketball students}}\)
= \(\frac{800 }{ 750}\)
= \(\frac{16 }{ 15}\)
Thus, the ratio of cricket students to basketball students is 16:15.
(c) Ratio of basketball students to total students:
= \(\frac{\text{Number of basketball students}}{\text{Total number of students}}\)
= \(\frac{750 }{ 1800}\)
= \(\frac{5 }{ 12}\)
Hence, the ratio of basketball students to total students is 5:12.
Number of students who chose basketball: 750
Number of students who chose cricket: 800
Number of students who chose table tennis: Total number of students - Number of basketball students - Number of cricket students
\(= 1800 - 750 - 800\)
\(= 250\)
(a) Ratio of basketball students to table tennis students:
= \(\frac{\text{Number of basketball students}}{\text{Number of table tennis students}}\)
= \(\frac{750 }{ 250}\)
=\(\frac{ 3 }{ 1}\)
So, the ratio of basketball students to table tennis students is 3:1.
(b) Ratio of cricket students to basketball students:
= \(\frac{\text{Number of cricket students}}{\text{Number of basketball students}}\)
= \(\frac{800 }{ 750}\)
= \(\frac{16 }{ 15}\)
Thus, the ratio of cricket students to basketball students is 16:15.
(c) Ratio of basketball students to total students:
= \(\frac{\text{Number of basketball students}}{\text{Total number of students}}\)
= \(\frac{750 }{ 1800}\)
= \(\frac{5 }{ 12}\)
Hence, the ratio of basketball students to total students is 5:12.
