- Question
- Raj invested some amount in ICICI bonds and put Mohan as the nominee. After the sudden death of Raj, Mohan got Rs. 31775 from the bonds. How much did Raj invest in the bonds?
(A) Raj died exactly 7 years from the date of his investment.
(B) The rate of interest is 15% p.a.
Correct Answer - (4)
Solution:
Statement A:
We can't conclusively state the invested amount without knowing the rate of interest. So statement A alone is not sufficient.
Statement B:
Without knowing the period of investment and method of interest (i.e. Simple or Compound Interest) we can't calculate the invested amount. So statement B alone is not sufficient.
Statement A and Statement B together:
Even after using the information provided in the statements A and B together we can't calculate the invested amount without knowing the method of interest (i.e. Simple or Compound Interest). Therefore, the answer choice is (4).
