AI explanation

The total number of students in the hostel speaking the three languages is 40 + 25 + 35 = 100. In a pie chart, the central angle for a specific category is found using the formula (Category Value / Total Value) multiplied by 360 degrees. For Hindi, the calculation is (40 / 100) multiplied by 360 degrees. This results in a central angle of 144 degrees.
