Question

simple interest on a sum of money is 9 by 16 of the sum if the rate is 41 by 2% per annum find the time​

Answer 1

let the sum=x

si=9/16x

rate=41/2 %

time=y

si=principal*time*rate/100

9x/16=x*y*41/2*100

9x*2*100/16=x*y*41/2

9x*1*100/8=x*y*41/2

9x*25*2/2=x*y*41

9x*25=x*y*41

9x*25/x=y*41

9*25=y*41

9*25/41=y

5.48=y

225/41=y

5whole 20/41 years=y

time  is 5 whole 20/41 years
