Answer 1

Answer:

8%

Step-by-step explanation:

Suppose, He borrowed Rs. X

So, His interest is Rs. (3X-X) = 2X            [As the amount trebled]

∴ interset of Rs. X in 25 yrs is Rs. 2X

       ,,        ,,   Rs. 1 in   1    yr  is Rs. ($\frac{2X}{X}$×$\frac{1}{25}$)

       ,,        ,,   Rs. 100 in 1 yr  is Rs.  ($\frac{2}{25}$×100) = 8

Ans. Rate of interest is 8%
