Answer:

Total number of students surveyed about their mode of transportation to school is 400.

Step-by-step explanation:

Here, given student who uses car as their mode of transport = 120 students

We have to find the total number of students who are surveyed.

Also, since complete circle represents 100% of data,

Total students who uses at least one mode of transport out of foot, bicycle, bus or car let it be x students.

Total percentage of students that uses bus, bicycle and on foot = (20 +15+35)% = 70%

Thus, percentage of students that uses car = 100 - 70 = 30%

Thus, 30 % of total students = 120

Mathematically,  30% of x = 120

Solving for x, we get,

\frac{30}{100} \times x=120

\Rightarrow x=120 \times \frac{100}{30}

\Rightarrow x=400

Thus, total number of students surveyed about their mode of transportation to school is 400.
