The compound interest and the simple interest on a certain sum for two years are Rs.2040 and Rs.2000 respectively.The rate of interest is same for both compound interest and simple interest.What is the principal?

C.I for 2 years for certain amount is, Ici=P(1+R%)2−P

⇒Ici=P[(1+R%)2−1]

⇒2040=P[(1+R%)2−1]

⇒2040=P[1+2R%+(R%)2−1]

⇒2040=P(2R%+(R%)2)

⇒2040=2PR%+PR%R%−−−−−−−−−(1)

S.I for 2 years for certain amount is, Isi=(2PR%)

⇒2000=2PR%——−(2)

And, PR%=1000−−−−−−−(3)

Putting the values of (2) and (3) in (1) we have,

2040=2000+1000R%

R%=401000

R%=4%

Then, 2000=2P4%

P=10004%

P=1000004

P=25000
