Correct Answer: 22,588
Explanation:
Flat rate = 12%
n = 4 × 4
= 16
Effective rate =2n/(n+1) × flat rate
Correct Answer: 32,240
Explanation:
Total cost = deposit + instalment amount × number of instalments
Correct Answer: 7125
Explanation:
total interest=1187.50*6
Correct Answer: 4.14
Explanation:
I = (P x T x R) /100
Correct Answer: Both I and II are not sufficient to answer
Explanation:
We know that, R = (100 x S.I) / (P x T)
Now I gives, S.I = Rs. 4000.
II gives, T = 4 years.
But, P is unknown. So, we cannot find R.
So, given data is insufficient to get R.
Correct Answer: 4months
Explanation:
t=I/pr
Correct Answer: 247.67
Explanation:
Suppose the merchant will take advantage of the cash discount of 4% of $20 000 = $800 by paying the bill within 30 days from the date of invoice. He needs to borrow $20 000 = $800 = $19 200. He would borrow this money on day 30 and repay it on day 100 (the day the original invoice is due) resulting in a 70-day loan. The interest he should be willing to pay on borrowed money should not exceed the cash discount $800.
r=I/pt=21.73%
The highest simple interest rate at which the merchant can afford to borrow money is 21.73%. This is a break-even rate. If he can borrow money, say at a rate of 15%, he should do so. He would borrow $19 200 for 70 days at 15%. Maturity value of the loan is $19 200(1+0.15(70/365))=$19 752.33
savings would be $20 000 ? $19 752.33 = $247.67
Correct Answer: 13841.89
Explanation:
Correct Answer: Both a and b sufficient
Explanation:
Let the sum be Rs. x
a. gives, S.I = Rs. 9000 and time = 9 years.
b. gives, Sum + S.I for 6 years = 2 x Sum
--> Sum = S.I for 6 years.
Now, S.I for 9 years = Rs. 9000
S.I for 1 year = Rs. 9000/9 = Rs. 1000.
S.I for 6 years = Rs. (1000 x 6)= Rs. 6000.
--> x = Rs. 6000
Thus, both a and b are necessary to answer the question.
Correct Answer: 6.66 %
Explanation:
Let the principle be Rs. P
As the amount double itself the interest is Rs. P too
So P = P x r x 15/100
=> r = 100/15 = 20/3 % = 6.66 %.
