Question

At what rate percent per year will a sum of Rs. 12000 amount to Rs. 12720 in a months?
​

Answer 1

Answer:

72%

Step-by-step explanation:

Given- Amt= Rs. 12720

           P= Rs. 12000

           I= 12720-12000

            = Rs. 720

           Time= 1 month

   Hence, Time= 1/12 year/s

Hence, I= (PRT)/100

            R= (I*100)/(PT)

              = (720*100*12)/(12000)

             = 72%
