 Welcome to the session. Let us just ask the following question. The question says, a bill of rupees 5,000 due on 13 June and another bill of rupees 4,000 due on August 25 were both discounted with a banker on April 1. If the difference between the two discounts is of 30 rupees, find a rate at which the discount is calculated. Now begin with the solution. Let the rate of discount be our percent. This is April 1 to 13 June. View date of second bill is 25 August. Case for which discount is charged on first bill counted on 1st April. Therefore, remaining days of April will be 29, 31 days in May and view date of first bill is 13 June. So, June will be 13 and this is equal to 73. This in a year that is 365 into our course in that is our by 100 and this is equal to 10 our second bill. Nine days in April is counted on 25th of 31 days in May is in June plus 31 days in July plus 25 days in August. This is equal to 146. Calculate, bankers discount on second bill is equal to 4,000 into 146 divided by 365 into our by 100 and this is equal to rupees 16 our. We are given that difference between is rupees 30 the required rate is 5%. This is our required answer. So, this completes the session by entity care.
