- Question
In how many years, Rs. 200 will produce the same interest @ 5 % as Rs. 900 produce in 2 years @ 3 ½ % ?
Options- A. 5.2 yrs
- B. 7 yrs
- C. 7.9 yrs
- D. 6.3 yrs
- Correct Answer
- 6.3 yrs
ExplanationP = Rs. 900, R = 3 ½ % = 7/2 %, T = 2 years.
Therefore,
S.I. = PTR/100
S.I. = Rs. (900 x 7/2 x 2/100) = Rs. 63
Now, P = Rs. 200, S.I. = Rs. 63, R = 5 %
Time = ((100 x 63) / (200 x 5) ) years = 6.3 years.

Correct Answer: Rs. 3.30
Explanation:
I = (600x11x5)/100 = 330 Paise = Rs. 3.30
Correct Answer: 18.75 %
Explanation:
Given,
S.I = 3 Principal Amount
=> 3A = A x 16 x R/100
By solving, we get
=> R = 18.75%
Correct Answer: 3.87
Explanation:
Let the two different rates of interests be r1 and r2 respectively.
From the given data,
Hence, the difference in the interest rates = 3.87
Correct Answer: 8%
Explanation:
We know,
S.I = PTR/100 where P = principal amount, T = time, R = rate of interest
Here in the given data,
Interest for two years S.I = 924 - 812 = Rs. 112
Now, Principal amount P = 812 - 112 = Rs. 700
Now,
R = S.I x 100/PT
R = 112 x 100/700 x 2
R = 11200/1400
R = 8%
Hence, the rate of interest R = 8%.
Correct Answer: $504
Explanation:
Cash price = $21 000
Deposit = 10% × $21 000 = $2100
Loan amount = $21000 ? $2100 = $18900
I=p x r x t/100
I=11340
Total amount = 18900 + 11340 = $30240
Regular payment = total amount /number of payments
Correct Answer: 16000
Correct Answer: 9.6%
Correct Answer: 1300
Correct Answer: Rs.156.25
Explanation:
Present worth = 169/(1+4/100)^n = 156.25
Correct Answer: Both I and II are necessary to answer
Explanation:
Given : S.I. = Rs. 50.
I gives, R = 10% p.a.
II gives, T = 10 years.
Sum = (100 x S.I)/(t x r ) = Rs.(100 x 50)/(10 x 10) = Rs.50
