Question

at what time the principal of rate 800 have simple interest of rate 125 at the rate of 12.5%

Answer 1

Hi ,

Principal = P = Rs 800

Rate of interest = R = 12.5% per annum

Interest = I = Rs 125

Let the Time = T years

We know that ,

I = PTR / 100

T = ( 100 × I ) / ( PR )

T = ( 100 × 125 )/ ( 800 × 12.5 )

After cancellation , we get

T = 10 / 8

T = 5/4 years

T = 1 year 3months

I hope this helps you.
