Answer:
(i) 7.14 %
(II) 5.35 %
Step-by-step explanation:
(i) Principal: 196 Rupee, Amount: 225 Rupee, and time: 2 years
Use the formula a=p(1+r)^t, where, where A: is the amount over the time of interest, P is the original interest, t is the number of years and r is the annual interest rate.
To do this:
225 = 196(1+r)^2
225/196 = (1+r)^2
1 + r = √225/196
1+r = 15/14
r = 15-14/14 = 1/14
r = 1/4 x 100 = 7.14 %
(II) Same thing again, with a TWIST!
Amount (in this case) = Principal +Compound interest = 3136 + 345 = 3481 Rupee
3481 = 3136(1+r)^2
3481/3136 = (1+r)^2
√3481/3136 = 1+r
√3481/3136 - 1 = r
r = 0.0535
r = 5.35 % (converted)
Hope this helps! Please mark as brainiest if so.
