Question:To find out the total compound interest accrued on a sum of money after `5` years, which of the following information given in the statements A and B is/are sufficient ?
A: the rate of interest was `6%` per annum.
B: The total simple interest on the same amount after `5` yaars at the same rate will be Rs.`600`
A only A is sufficient
B Either A or B is sufficient
C Both A & B together are needed
D Only A is sufficient
+ ExplanationUsing A and B both, we may calculate :
Sum`= ((100 xx 600)/(6 xx 5))`
`= Rs. 2000`.
So,the compound interest may be obtained.
Thus, both A and B together are needed.
