Correct Answer: 15%
Explanation:
Let the rate be R% p.a. Then,
Rate = 15%.
Correct Answer: 4 years
Explanation:
> 2P
Now, (6/5 x 6/5 x 6/5 x 6/5) > 2.
So, n = 4 years.
Correct Answer: 5%
Explanation:
C.I =
594.5 =
% .
Correct Answer: Rs. 704
Explanation:
We know that,
From given data, P = Rs. 8625
Now, C.I =
Correct Answer: 2.04
Explanation:
C.I. when interest
compounded yearly=rs.[5000*(1+4/100)(1+1/2*4/100)]
= Rs. 5304.
C.I. when interest is
compounded half-yearly=rs.5000(1+2/100)^3
= Rs. 5306.04
Difference = Rs. (5306.04 - 5304) = Rs. 2.04
Correct Answer: 1080
Explanation:
Let the sum be Rs. x. Then,
Thus, the sum is Rs. 2160
Correct Answer: Rs.8820

Amount
=Rs.[8000x(1+5/100)²]
= Rs.[8000 x 21/20x21/20]
= Rs.8820.
Correct Answer: Rs. 1901
Explanation:
P = Rs. 15225, n = 9 months = 3 quarters, R = 16% p.a. per quarter.
Amount =
= (15225 x 26/25 x 26/25 x 26/25) = Rs. 17126.05
=> C.I. = 17126 - 15625 = Rs. 1901.05.
Correct Answer: 21 percent
Correct Answer: Rs. 1100
Explanation:
Let the sum be Rs.x. Then,
=> x =5500
