$\rule{400}4$

☆ ANSWER:-

♤ 16 students

$\rule{400}4$

▪︎ Given:-

• Total number of students = 48.

• Fraction of students choose maths = 2/3.

• Rest of the students choose computer science.

▪︎ To Find:-

• Number of students choose computer science.

$\rule{400}2$

▪︎ So,

• Let us find the number of students who choose maths.

• Lets denote the number of students like maths by m.

$\sf \mapsto \: m = \frac{2}{\cancel{3}} \times \cancel48. \\ \\ \sf \mapsto \: m =2 \times 16. \\ \\ \sf \mapsto \: m = 32.$

▪︎ Therefore number of students choose maths are 32 out of 48.

$\rule{400}2$

▪︎ Also,

• Rest of the students choose computer science.

• Lets denote the number of students choose computer science by c.

$\sf \mapsto \: c = 48 - 32. \\ \\\sf \mapsto \: c = 16 .$

▪︎ Therefore number of students choose computer science are 16.
