Correct Answer: 2562.5
Correct Answer: 1452
Correct Answer: 64000
Correct Answer: 15000
Correct Answer: Rs 1134
Correct Answer: 40000
Correct Answer: Rs.1261
Explanation:
Clearly, Rate = 5% p.a .,
Time = 3 years
S.I =Rs.1200.
So,Principal
=Rs.(100 x 1200/3x5)
=Rs.8000.
Amount
=Rs.[8000 x (1+5/100)³]
=Rs(8000x21/20x21/20x21/20)
= Rs.9261
C.I
=Rs.(9261-8000)
=Rs.1261.
Correct Answer: 2
Explanation:
Amount = Rs. (30000 + 4347) = Rs. 34347
(1+7/100)^n=34347
Correct Answer: Either I or II alone sufficient to answer
Explanation:
I. Amount =
II. Amount =
Thus, I as well as II gives the answer.
Correct Answer: 5.65%
Explanation:
We are not given a value of P in this problem, so either pick a value
for P and stick with that throughout the problem, or just let P = P.
We have that t = 1, and r = .055. To find the effective rate of interest,
first find out how much money we have after one year:
A = Pert
A = Pe(.055)(1)
A = 1.056541P.
Therefore, after 1 year, whatever the principal was, we now have 1.056541P.
Next, find out how much interest was earned, I, by subtracting the initial amount of money from the final amount:
I = A ? P
= 1.056541P ? P
= .056541P.
Finally, to find the effective rate of interest, use the simple interest formula, I = Prt. So,
I = Pr(1) = .056541P
.056541 = r.
Therefore, the effective rate of interest is 5.65%
