ANSWER:
The percentage of students attended the college is 80%.
SOLUTION:
Given, there are 35 students in class.
On a certain day 28 students were present.
We need to find what percent of students came to school.
We know that,
Attended students percentage =
![$\frac{\text {number of students present}}{\text {total strength of the class}} * 100$](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7zmq43opcyohwr59lg85h7zi0s4vvugb52.png)
Here, total strength = 35 and number of students present = 28.
Now, Attended students percentage =
![$(28)/(35) * 100$](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jdss8xki7aztpcwl1x8nbp5g4o5d5rz15w.png)
![$=(4)/(5) * 100$](https://img.qammunity.org/2020/formulas/mathematics/middle-school/yqn68pqj4od37mpy5qyv1gwwarlmno304f.png)
= 4 x 20 = 80
Hence, the percentage of students attended the collage is 80%.
