True discount is the simple interest on the present worth of a debt for the time remaining until it is due. This set asks you to find the rate percent from a given discount, the amount of a bill from its true discount, and the sum due when the discount, rate and time are known. Other questions compare a cash offer with a credit offer, or find the present worth of equal instalments. A useful relationship is that the simple interest on the amount minus the true discount equals the simple interest on the true discount.

True discount is the difference between the amount due at a future date and its present worth. It equals the simple interest on the present worth for the remaining time. So present worth plus true discount equals the amount due, and present worth equals amount times 100 divided by 100 plus rate times time.
The present worth is 2,562 minus 122, which is Rs 2,440. True discount is the interest on this for one third of a year, so 122 equals 2,440 times R times one third divided by 100. Solving gives a rate of 15 percent per annum.
