Question

in what time will Rupees 1500 amount to rupees 1747.50 when invested at a simple interest of 3% per annum​

Answer 1

Step-by-step explanation:

We know that SI = P×R×T by 100 but we don't know SI and T (time). A= SI - P. A=1747.5, SI=?, P=1500. 1747.5 =? - 1500. 1747.5+1500 =?. 3247.5=?(SI). 3247.5 = 1500×3×T÷100. 4500×T ÷ 100. 45×T because when u will divide 4500 by 100 u will get 45. 3247.5=45×T. 3247.5÷45=T. because 45/is multiplied with T and by changing its side it will divide 3247.5. T= 72.166667 months. Divide it by 12. 72.166667/12=almost 6 years
