SSC CPO SI and ASI Model Paper 10

(3) Since S.I. for 3 years = ₹900
Therefore S.I. for 1 year = ₹300
Let initial principal = P
Now 6% of P = ₹300
⇒P = ₹5000
C.I. for 1st year = 6% of 5000= ₹300
C.I. for 2nd year = 6% of (5000 +300) = ₹318
C.I. for 3rd year = 6% of (5000 +300 + 318) = ₹337.08
Difference between C.I. and S.I. for3 years = (337.08 + 318 + 300) -900 = ₹55.08
