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.

Principal 5000 and 4 p.a.
1 year 200 intrest he has to pay,
The same amount 6(1/4)%,
6(1/4)is the mixed fraction,
When you change this;
25/4.
25/4% / 100% x 5000.
U get 312.50.
200-312.50 = 112.50.
So he gains 112.50;

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.

Why we are taking 25/4 instead of 6/4?
=> 25/4 = 6.25 and 6/4 = 1.5 then, how both are equal?
Why are we adding 6+1/4?
=> 25/4 = 6.25 and 6/4 = 1.5 then, how both are equal?
Why are we adding 6+1/4?
