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. 7:5, respectively Let the total profit received by them be Rs. 100x Therefore, profit distributed between ‘A’ and ‘B’ = 0.75 × 100x = Rs. 75x Profit received by ‘A’ = 75x × (7/12) = Rs. 43.75x According to the question, 43.75x = 1764 => x = 40.32 Therefore, total profit received by ‘A’ and ‘B’ = 100x = Rs. 4032
