The line graphs show the profit (in lakh rupees), for 6 years, of two companies A and B. The ratio of the cumulative profits for these 6 years of Company B to Company A is:
3 : 7
Total profit in 6 years by company B = (30 + 20 – 10 + 20 – 20 – 10) lakh = 30 lakh
Total profit in 6 years by company A = (20 + 10 – 10 + 0 + 20 + 30) lakh = 70 lakh
∴ Required ratio = 30 : 70 = 3 : 7
