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;
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;

At the place of 25/4, we can write 6.25 which is equal to 25/4. And also we can say (6+1/4) year = 6.25.

Hi Basudev,
We can write 6(1/4) as 25/4. Both are equivalent to 6.25
I hope you understand what I have mentioned here. Have a nice day!

Its very simple 25/4 is the rate of interests at which he lends it to other person
just find s.i. of 5000,4%,2
and 5000,25/4%,2
and subtract the both pls refer 8th std maths book.

The difference between the interests is 2.25.
So interest at 2.25 for 1 year on 5000 is the gain for 1 year
= (2.25/100) x 5000 x 1
= 112.5
So interest at 2.25 for 1 year on 5000 is the gain for 1 year
= (2.25/100) x 5000 x 1
= 112.5
