Question

If the difference between the simple interest and compound interest us rs. 200 at 4% for 2 years on certain principal, then find the principal.

Answer 1

Answer:

principal=rs.125000

Step-by-step explanation:

diff between si and ci for 2 years =P(R/100)(R/100)

(R/100) whole square since i cannot put square i have done it with 2 times

200=P(4/100)(4/100)

P=200*100/4*100/4

=125000

Answer 2

Answer:

Step-by-step explanation: let p= x

x*8.16/100 - x*4*2/100=200

8.16x-8x/100=200

.16x=20000

.16x/10=20000

X=200000/16

X=12500
