A pie-chart represents profit of the companies A, B and C. If total profit of three companies is 720 lakh and angle of pie-chart corresponding to company A is 120°, then profit of A (in lakh) is

The correct answer is (b).

The profit of company A is equal to its angle in the pie chart multiplied by the total profit of the three companies. The angle of company A is 120° and the total profit is 720 lakh, so the profit of company A is 120°/360° * 720 lakh = 240 lakh.

Option (a) is incorrect because it is the angle of company A, not the profit.

Option (c) is incorrect because it is twice the profit of company A.

Option (d) is incorrect because it is the total profit of the three companies, not the profit of company A.
