Study the pie-chart and answer the question. In an institute, there are 900 students who use different modes of transport for to and from travel. The given pie diagram represents the requisite data. The number of students who travel on foot is:

175  150 225 180

175

Total number of students = 900 Number of students who travel on foot = \(\frac{70º }{360º }\) × 900 = 175
