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% |

Is it like
Amount= P + S.I
Amount= P + (P*T*R)/100 ?
Amount= P + S.I
Amount= P + (P*T*R)/100 ?

In that question we are having 3 rate values,so we substitue one by one values then we get the corrct values.for example:
p=12500
n=4
r=3 or 4 or 5 or 6
If we sub:3
12500*4*3/100=1500
1500+12500=14000,we are not getting the correct amount value then
We sub another,
12500*6*4/100=3000
3000+12500=15500,
Now we got the correct value.
p=12500
n=4
r=3 or 4 or 5 or 6
If we sub:3
12500*4*3/100=1500
1500+12500=14000,we are not getting the correct amount value then
We sub another,
12500*6*4/100=3000
3000+12500=15500,
Now we got the correct value.

The calculation used to calculate rate gives out 30 as the answer.
[(3000 x 100)/(12500 x 4)] = 30. NOT 6.
Can anyone throw a light on this?
[(3000 x 100)/(12500 x 4)] = 30. NOT 6.

Here, 6 is the correct answer.
15500-12500=3000.
Formula:
SI=PNR/100.
3000=12500*4*R/100.
3000*100/12500*4=R.
300000/50000=R.
R=6%.
15500-12500=3000.
Formula:
SI=PNR/100.
3000=12500*4*R/100.
3000*100/12500*4=R.
300000/50000=R.
R=6%.

Here SI=PTR/100
So, SI=15500-12500=3000. P=12500, T=4YER,
SO 3000=12500*4*R/100,
i.e R=3000/500= 6% answer.
So, SI=15500-12500=3000. P=12500, T=4YER,
SO 3000=12500*4*R/100,
