Answer: The ratio of total revenue of company P to company Q during 2013–2018 = 16 : 17. Answer: B. 16 : 17.
Write total revenue formula for each company: Since investment I is equal for both companies, let I = 1 unit. Total Revenue_P = sum of (1 + p_P/100) for each year = 6 + (sum of P profit %s)/100. Similarly for Q.
Read profit % sums from bar graph: From the bar graph (2013–2018): sum of P's profit % = 200; sum of Q's profit % = 250. Thus Total Revenue P = 6 + 200/100 = 8.00 (per unit I), Total Revenue Q = 6 + 250/100 = 8.50.
