How it is possible?
Because here the rate of interest is different for each 2 years. So he gains transaction each year is also different. So the person who is intelligent please clear my concept.

In this question, it is mention that person lends the amount to another person at (6 1/4) 25/4 pa not 25/4pc. then how come we are considering this 25/4 as a percentage?
The answer should be RS. 310.5 according to question. Can anyone clear my this doubt?

@All.
One can avoid the calculations by simply taking the amount of increase in the rate of interest.
i.e
Gain rate --> 25/4 = 6.25%.
Original Rate --> 4%.
increase = 2.25%.
Therefore, Gain = (5000x2.25)/100 = 112.5 Rs.

How it is 2/100? Can anyone explain me?

2 denotes the number of years.
i.e T, and R % = 6 1/4 = 25/4 % ie 25/(4x100).
i.e T, and R % = 6 1/4 = 25/4 % ie 25/(4x100).

6 (1/4) can written as ((6*4)+1)/4. i.e 25/4.

(5000*25)/400 - (5000*4)/100 = 112.50.

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?
