400rs is right answer

Step-by-step explanation:

Interest for two years =Rs.568−Rs.520=Rs.48

∴S.I.for1year=Rs.

2

48

=Rs.24

∴S.I.for5years=5×Rs.24=Rs.120

∴ Principal =Amount−S.I.

=Rs.520−Rs.120=Rs.400.

Answer 2

Answer:

Principle = 350

Step-by-step explanation:

In this we have to get principle so we take the formula:-

P = SI×100

P×R

P = 520×100

5×4

P = 52000

20

P = 350
