▶ Question - If marks gives am intrest of Rs. 45 for one year at 9% rate per annum , what is the sum she has borrowed ?



▶ Given :-


Internet ( SI ) = Rs. 45


Time ( T ) = 1 year


Rate of interest ( R% ) = 9%



▶ Explanation :-


Principle ( or ) Sum = SI × 100 / R% × T


Principle = 45 × 100 / 1 × 9


Principle = 4500 / 9


Principle = Rs. 500


∴ Sum borrowed by Mark = Rs. 500
