Question

ln what time will ₹3600 amount to₹4320 at 8% per annum simple interest

Answer 1

Amount=4320
Sum=3600
Si=a-s(p)
Si=4320-3600=720
Si=prt/100
720=3600x8xt/100
T=2 and half year

Answer 2

Hi ,

Principal ( p ) = Rs 3600

Amount ( A ) = 4320

Rate of interest ( r ) = 8%

Time = t years

Simple interest ( I ) = A - p

I = 4320 - 3600

= Rs 720

t = ( 100 × I )/pr

= ( 100 × 720 ) / ( 3600 × 8 )

= 5/2

= 2 1/2 years

I hope this helps you.
