In a school, 91.66% opted for science
and half of the remaining opted for
commerce and remaining 20 opted for
arts. Find total number of students.​

Answer 1

Answer:

Step-by-step explanation:

91.66 % is science

remaining 8.34% is commerce + arts

8.34%/2 =4.17 %

4.17%=20 students

4.17% commerce +4.17% arts =8.34% remaining

20+20=40

now 8.34% =40

then 100% =480

so 480 is the ans.

Enjoy.

Answer 2

Given:

91.66% opted for science

To find:

The total number of students.

Solution:

Let the total number of students are 100%

It is given in the question that 91.66% opted for science and

half of the remaining opted for commerce

We have remaining 8.34% students and half of it is 4.17%

Remaining 20 opted for arts

so, other 4.17% will be equal to 20

• 4.17% ----- 20
• 100% ----- 20×100/4.17
• 100% ----- 479.616

So we have total 479 students
