Since, ‘A’ and ‘B’ invested their sums for equal period, therefore, ratio of the profit received by ‘A’ and ‘B’ will be equal to the ratio of sum invested by them i.e. 8:5, respectively Let the total profit received by them be Rs. 100x Therefore, profit distributed between ‘A’ and ‘B’ = 0.78 × 100x = Rs. 78x Profit received by ‘A’ = 78x × (8/13) = Rs. 48x According to the question, 48x = 2556 => x = 53.25 Therefore, total profit received by ‘A’ and ‘B’ = 100x = Rs. 5325
