Question

the difference between simple and compound interest for 2years at 5% per annum is 25 Rs. The sum is...?​

Answer 1

Answer:

simple intrest = ptr /100.

p = ₹.25.

t = 2 year's.

r = 5% per annum.

now S I = 25*2*5/ 100.

= 250/100.

= 2.5.

compound interest = amount - principal.

100 = a - 25.

amount = 100 - 25 = 75.

sum = 75 + 25 = 100.
