Question

in what time will Rs 10000amount to Rs 12100at 10.%per annum compounded annually

Answer 1

Hey,
Amount =P(1+r/100)T
12100=10000(1+10/100)T
12100/10000=(11/10)T
(11/10)^2=(11/10)T
Now,(11/10) is cancelled on both sides,
So, Time=2yrs.
Hope this helps you buddy!!

Answer 2

For 1st year
Total amount = 10000 + (10000*10)/100
Total amount = 11000

For 2nd year
Total amount = 11000 + (11000*10)/100
Total amount = 12100

Total time is 2 years
