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: Both I and II are necessary to answer
Explanation:
Let the rate be R% p.a.
I gives, P = Rs. 8000 and T = 4 years.
II gives, S.I = Rs. (8800 - 8000) = Rs. 800.
R = [100 x S.I] / [p x t ]= (100 x 800)/(8000 x 4) = 2 ½ % p.a
Thus, I and II both are needed to get the answer.
Correct Answer: 8500
Explanation:
P = 68000, R = % & T = 9 months (3/4 years)
Correct Answer: Both I and II are necessary to answer
Explanation:
Let the sum be Rs. x.
I gives, S.I. = Rs. 7000 and T = 7 years.
II gives, Sum + S.I. for 5 years = 2 x Sum Sum = S.I. for 5 years.
Now, S.I. for 7 years = Rs. 7000.
therefore, S.I. for 1 year = Rs. 1000.
Thus, I and II both are needed to get the answer.
Correct Answer: 6%
Explanation:
1. To find the interest, subtract the principal from the balance.
$618 - $600 = $18
2.Use the simple interest formula and solve for r.
I = Prt
18= 600 x r x (1/2)
r= 0.06 =6%
Correct Answer: 7125
Explanation:

Effective rate =2n/(n+1) × flat rate
Correct Answer: 15615.52
Explanation:
I = prt = [15000 × 0.07 × (214/365) ]=615.52
Future value, S = P + I = $15 000 + $615.52 = $15 615.52
Correct Answer: 4months
Explanation:
t=I/pr
