Question

in what time will rupees 3600 amount to Rupees 4410 at 9% per year simple interest

Answer 1

A=p(1+RT/100)
4410=3600(1+9T/100)
4410/3600=1+9T/100
441/360-1=9T/100
441-360/360=9T/100
81/360÷9=T/100
9/360=T/100
100/40=T
T=2.5 years

Answer 2

A=p(1+RT/100)
4410=3600(1+9T/100)
4410/3600=1+9T/100

441-360/360=9T/100
81/360÷9=T/100
9/360=T/100
100/40=T
T=2.5 years
