Question

S.I on a sum for 3yrs at any rate of interest is 450 while C.I on the same sum at the same rate for 2yrs is 315. Find the sum and rate percent?

Answer 1

Principal

1 st year = 150

2 nd year = 150

:

15

15=10% of 150

so R=10%

P=$15\times 100=1500$

$\therefore$ rate % = 10% and sum = rs 1500.
