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

Every thing here is fine but at last why did you take average of the gain 225/2=125.50.
Please clarify my doubt.

Actually you are taking 2 years know that is in which the loan lends to another person but we want actual gain if 2 years is 225 means for 1 year 225/2=112. 5 ok.

Simplest method to solve
Principle is same
Term i.e period is same
ONLY lending & borrrowing rate differs
So GAIN=Diff between them(25/4-4)% = 9/4%
Therefore gain in rupees = 5000*9/4% = 112.5

What is not clear in the qn is whether the interest is lent or the amount is lent after two years?
