The pie chart given below shows the percentage of time taken by different processes in making a car.

Question 100

15% of total time is spent on quality check and this time is equally taken from all other processes. So What will be the new sectorial angle (in degrees) made by total time of seats and glass?

Solution

Time spent on quality check = 15%

As this time is taken equally from the 6 processes, thus time in each process will be reduced by = $$\frac{15}{6}=2.5\%$$

Initial time taken by seats and glass = 6+8 = 14%

New time taken by seats and glass = $$(6-2.5)+(8-2.5)=9\%$$

=> Sectorial angle = $$\frac{9}{100}\times360$$

= $$9\times3.6=32.4^\circ$$

=> Ans - (B)
