The pie chart given below shows the break-up of number of hours of teaching various subjects at an institute by Mr. Raghav.

Question 100

A new topic named Problem Solving was also introduced and it was decided that 10% time of all topics except Arithmetic will be devoted to it. What will be the central angle (in degrees) made by Problem Solving in the new pie chart?

Solution

Total time (in %) given to all topics except arithmetic = (100-46)% = 54%

=> Total time (in %) given to problem solving = $$\frac{10}{100}\times54=5.4\%$$

$$\therefore$$ Central angle = $$\frac{5.4}{100}\times360$$

= $$19.44^\circ$$

=> Ans - (C)
