Following pie chart represents expenses on different items in construction of a room. If total expenses in construction of the room are Rs. 2,00,000, then how much money was expended on labour?

Correct option is B

Total angle in a pie chart = 360°
Angle of the labour component in the pie chart = 360 – 54 – 108 – 36 – 72 = 90°
Money expended on labour = (90/360) x 200000 = 50000
So, money expended on labour = 50,000 /-
