hence rate interest r = 41.176%

Step-by-step explanation:

The amount borrowed= $680

amount payed back = $750

therefore, interest incurred = 750-680= $70

time, t= 3 months = 3/12= 0.25 years

rate%, r

we know that SI= $\frac{PRT}{100}$

70= $\frac{680\timesr\0.25}{100}$

r= $\frac{7000}{0.25\times680} = 41.176$

hence rate interest r = 41.176%
