He got for 4% and he gave for 6 1/4% which is gain for him;
Now simply,
25/4 -4 =9/4%.
9/4% of 5000 is 112.5.
Now simply,
25/4 -4 =9/4%.
9/4% of 5000 is 112.5.

The difference in rate percentage will be the profit so, (6 1/4% - 4%)per year = 2.25%per year
P=5,000 considered as total percentage i,e 100.
Therefore, by cross multiplication;
5,000 = 100%
? = 2.25 %
We get;
5,000 x 2.25/100.
= 112.50 answers solved.
Question asked only for 1 year so it is 112.50.
In case if it is for two years it will be (112.50+112.50),
= 225.

Another method:
Gain percentage = 6 1/4% - 4%.
Gain percentage = 25/4% - 4%.
Gain percentage = 9/4%.
We know that principle amount, 5000rs = 100%.
Then,.
x rs = 9/4%.
x = (50 * 9)/4,
x = 450/4,
x = 112.5rs.
Gain percentage = 6 1/4% - 4%.
Gain percentage = 25/4% - 4%.
Gain percentage = 9/4%.
We know that principle amount, 5000rs = 100%.
Then,.
x rs = 9/4%.
x = (50 * 9)/4,
x = 450/4,
x = 112.5rs.

CASE 1:
P = 5000, T = 2, R = 4%.
CASE 2:
P=5000, T = 2, R = 6.25%.
GAIN = 6.25% - 4%.
= 2.25%.
NOW, 5000*2.25% = 112.5( FOR 1 YEAR).
P = 5000, T = 2, R = 4%.
CASE 2:
P=5000, T = 2, R = 6.25%.
GAIN = 6.25% - 4%.
= 2.25%.
NOW, 5000*2.25% = 112.5( FOR 1 YEAR).

@Himanshu Baghel
Ans:
For,1st person P=x.
2nd person=15000-x.
So, SI=3870.
(x*10*3)/100+[(15000-x)*7*3]/100=3870.
After calculation answer will be 8000.

@Himanshu.
x + y = 15000,
0.3x+ 0.21y = 3870,
y = 15000 - x.
Solving we get x = 8000 and y = 7000.
So the sum given to A is 8000.
x + y = 15000,
0.3x+ 0.21y = 3870,
y = 15000 - x.
Solving we get x = 8000 and y = 7000.
So the sum given to A is 8000.

Why was 225 divided by 2 in the last step?
Vallabha chebiyyam said:

Because 225 is the gain for 2 years(read the Q)
we need to calculate for only 1 year so, 225/2=112.5.
