A and B invested Rs.2x and Rs.2400 in a scheme at simple interest at 8% p.a. The investment time of B is 1 year more than that of
A.The ratio of interest obtained by A and B is 4:29 respectively. Find the difference between the interests obtained by A and
B.

The given ratio of interests obtained by A and B is 4:29. We have two variables, x (related to the investment amount by A) and t (the time period), and only one equation derived from the ratio provided. Why It Can't Be Determined: The problem involves two variables (x and t), but there is only one equation linking them. Thus, there is insufficient information to find unique values for both x and t. Without additional constraints or a direct relationship between x and t, it is impossible to calculate the exact interest amounts or their difference. Hence, The answer is "can't be determined" because we lack enough information to solve for both x and t uniquely.
