The true discount on a bill due 9 months hence at 12% per annum is Rs. Find the amount of the bill and its present worth.

Correct Answer: 6000

Let amount be Rs. x. 


Then,  [X * R * T] / [100+(R * T)]  


x × 12 × 3 4 100 + 12 × 3 4   =   540  


x=  Rs.6540  


Amount = Rs. 6540.  


P.W. = Rs. (6540 – 540) =Rs. 6000.
