The following pie-chart shows the study - time of different subjects of a student in a day. Study the pie chart and answer the following questions.
If the student spends 15% instead of 10% on others, and that 5% is taken from mathematics, then the difference in study time for mathematics (when studying 20 hours/day) is
1 hour
Earlier time spent on others = 10% of 20 = 2 hrs.

Hence, loss in math time = 1 hour. Therefore, the correct answer is 3) 1 hour.
