Correct Answer: 60
Correct Answer: 1.2 Paise
Explanation:
Given Principal amount P = Rs. 10
Time T = 4 months
Rate of interest R = 3 ps
Interest I = PTR/100 = (10 x 4 x 3)/100 = 12/10 = 1.2 paise.
Correct Answer: Rs. 432
Explanation:
Here Avinash gave to Rajeev and Rajeev gave the same to Chanukya
Principal amount and Time is same but the only difference is Rate of interest.
Rajeev took @ 8% and gave it to Chanukya @ 6%
Here the difference in interest rate = 2%
2% of 5400 should be the extra amount paid by Rajeev to Avinash
Required amount =
Hence, Rs. 432 is the extra amount has to be paid by Rajeev to Avinash after 4 years.
Correct Answer: Rs. 316
Explanation:
S.I. for 2 years = (514 - 415) = Rs. 99
S.I. for 1 year = 99/2
Principal = (415 - 99) = Rs. 316.
Correct Answer: 8.16 %
Explanation:
Let the sum be Rs. 100. Then,
S.I. for first 6 months = (100 x 8 x 1) / (100 x 2) = Rs. 4
S.I. for last 6 months = (104 x 8 x 1) / (100 x 2) = Rs. 4.16
So, amount at the end of 1 year = (100 + 4 + 4.16) = Rs. 108.16
Effective rate = (108.16 - 100) = 8.16%.
Correct Answer: Rs.300
Correct Answer: Rs. 8000
Explanation:
Let the amount at 6% be x
Amount at 10% be (10000 ?x)
At 9.2 % interest, SI = 10000 X 9.2 X 1/100 = 920
Amount = 10920
? 6x/100 + (10000 ? x)10/100 = 920
? 6x ? 10x + 100000 = 92000
? 4x = 8000
? x = 2000
Money lent at 10 % = 10000 ? 2000 = 8000
Correct Answer: 8
Correct Answer: 12 percent
Correct Answer: 6643.0125
