A sum of Rs. 12,500 amounts to Rs. 15,500 in 4 years at the rate of simple interest. What is the rate of interest?
Answer: Option
Explanation:
S.I. = Rs. (15500 - 12500) = Rs. 3000.
| Rate = |  |
100 x 3000 |  % |
= 6% |
| 12500 x 4 |

--> 12500*6% = 750.
---> 750*4 = 3000.
---> 12500+3000 = 15500.
Answer: 6%.
---> 750*4 = 3000.
---> 12500+3000 = 15500.
Answer: 6%.

12500*6% = 750.
750*4 = 3000.
12500+3000 = 15500.
750*4 = 3000.
12500+3000 = 15500.

Here.
P = 12500.
T = 4 years.
Amount = S.I+P.
S.I = Amount-P.
S.I = 15500-12500 = 3000.
R = 100*S.I/P*T = 100*3000/12500*4 = 6%.
P = 12500.
T = 4 years.
Amount = S.I+P.
S.I = Amount-P.
S.I = 15500-12500 = 3000.
R = 100*S.I/P*T = 100*3000/12500*4 = 6%.

4.65*10 = 46.5.
46.5*2 = 93.
Hence 20 days.
46.5*2 = 93.
Hence 20 days.

We have a 12500 amount & after 4 year, we get 15500 amount so total.
Profit amount or S.I in 4 Year is 3000.
Now use the Formula:.
S.I = (P*R*T) /100.
Profit amount or S.I in 4 Year is 3000.
Now use the Formula:.
S.I = (P*R*T) /100.

Amount = principal + simple interest.
Dats why we subtracted amount and principal to have the simple interest.

Still I deosn't understand why we have to consider SI as sub 1550 from12500.
