 Hello friends and how are you all today? The question says, what is the face value of bill discounted at 5% per annum, 73 days earlier than its legal due date, the bankers gain being rupees 10. So here, let the face value of the bill be rupees S. Rate of interest is given to us as 5% per annum that is 1 by 20. We are given the time period that is the period of discount as 73 days. That is 73 by 365 year which on simplifying can be written as 1 by 5. Yeah. Now, we are given that bankers gain is equal to bankers discount minus true discount isn't it? We are given bankers gain as rupees 10. So we have rupees 10 equal to SRT minus SRT upon 1 plus R which further implies 10 is equal to S into R that is 1 by 20 into T that is 1 by 5 minus SRT again that is S into 1 by 20 into 1 by 5 divided by 1 plus R into T that implies 10 is equal to S upon 100 minus S upon 100 divided by 1 plus 1 upon 100. Simplifying it further we have 10 is equal to S by 100 minus S by 100 into 100 upon 101. Further on solving we find out that 10 is equal to S upon 100 minus S upon 101 which on further simplifying gives us 10 into 100 into 101 is equal to 101 S minus 100 S. It is after taking LCM and further simplifying so we have 101 000 equal to S. Therefore this value of the bill is rupees 1 lakh 1000. Right. So this completes the session hope you understood it well and enjoyed it too have a nice day.
