​The above pie-chart shows the amount spent by each of the departments on their annual functions. Find the amount spent by Admin and HR, if L and D expense amounts to ₹6,400.​

Correct option is C

Solution:

L& D expense amount = ₹ 6,400

Angle value for L & D = 40°

Angle value for Admin and HR = 100° + 90° = 190°  

Now according pie-chart 

40° = ₹ 6,400  

​$$1° = \frac{6400}{40}$$​​

190° = $$\frac{6400}{40}\times 190$$​​

190° = 30400 

Thus the amount spent by Admin and HR is ₹ 30,400 .
