A. Rs.460
B. Rs.5640
C. Rs.5460
D. Rs.5604
Answer
Correct Answer: C. Rs.5460
A. Rs.460
B. Rs.5640
C. Rs.5460
D. Rs.5604
Correct Answer: C. Rs.5460
A. Rs.9630
B. Rs.9680
C. Rs.9610
D. None of these
Correct Answer: B. Rs.9680
A= P{1 + R/100}n
=> 8000{1 + 10/100}22 = Rs.9680
A. Rs.18,828.80
B. Rs.19,828.80
C. Rs.18,028.80
D. Rs.17,828.80
Correct Answer: B. Rs.19,828.80
Let the sum be Rs.P
P{ [ 1 + 8/100]2 – 1 } = 2828.80
P(8/100)(2 + 8/100) = 2828.80 [a2 – b2 = (a – b) ( a + b)] P = 2828.80 / (0.08)(2.08) = 1360/0.08 = 17000 Principal + Interest = Rs. 19828.80
A. Rs.4273
B. Rs.4613
C. Rs.4064
D. Rs.4266
Correct Answer: D. Rs.4266
CI = 14800{ [ 1 + 13.5/100]2 – 1 }
= 14800 { [1 + 27/200]2 – 1
= 14800 { 2 + 27/200}{27/200}
= (74)[2 + 27/200](27) =
1998[2 + 27/200] = 3996 + 269.73 = Rs. 4266
A. 8% p.a
B. 6% p.a
C. 4% p.a
D. 5% p.a
Correct Answer: D. 5% p.a
Let the rate of interest be R% p.a.
17400[1 + R/100]2 = 17400 + 1783.50
[1 + R/100]2 = (17400 + 1783.50)/17400
= 1 + 1025/10000 = 1 + 41/400
= 441/400 = [21/20]2
[1 + R/100] = 21/20
R/100 = 1/20
Therefore R = 5
A. 18% p.a
B. 22% p.a
C. 20% p.a
D. 24% p.a
Correct Answer: C. 20% p.a
Rs.1440 – 1200 = Rs.240 is the interest on Rs.1200 for one year.
Rate of interest = (100 * 240) / (100 * 1) = 20% p.a
A. Rs.2520
B. Rs.3120
C. Rs.3320
D. Rs.2760
Correct Answer: B. Rs.3120
Let A be the amount received at the end of the three years.
A = 4800[1 + 10/100][1 + 20/100][1 + 25/100]
A = (4800 * 11 * 6 * 5)/(10 * 5 * 4)
A = Rs.7920
So the interest = 7920 – 4800 = Rs.3120
A. Rs.500
B. Rs.250
C. Rs.5012.50
D. None of these
Correct Answer: D. None of these
Let the principal be Rs.P
S.I at 5% p.a in 8 years on Rs.P = Rs.500
(P)(8)(5)/100 = 500
P = 1250
C.I on Rs.2P i.e., Rs.2500 at 5% p.a in two years
= 2500{ [1 + 5/100]2 – 1} = 2500{ 212 – 202 /202}
= 2500/400(441 – 400)
= 25/4(41) = 1025/4 = Rs.256.25
A. Rs.20043.94
B. Rs.18654.81
C. Rs.20264.46
D. Rs.19612.41
Correct Answer: A. Rs.20043.94
Let the rate of interest be R% p.a.
(49500)(3)(R)/100 = 17820
495R = 5940
R = 12
CI on Rs.49500 at 12% p.a. for three years
= 49500{[1 + 12/100]3 – 1} = 69543.936 – 49500 = Rs.20043.94
when rounded off to two decimal places.
A. Rs.10,840
B. Rs.10,720
C. Rs.10,560
D. Rs.10,280
Correct Answer: C. Rs.10,560
Let the rate of interest be R% p.a.
4400{[1 + R/100]2 – 1} = 11193.60
[1 + R/100]2 = (44000 + 11193.60)/44000
[1 + R/100]2 = 1 + 2544/1000 = 1 + 159/625
[1 + R/100]2 = 784/625 = (28/25)2
1 + R/100 = 28/25
R/100 = 3/25
Therefore R = 12 SI on Rs.44000 at 12% p.a. for two years = 44000(2)(12)/100
=Rs.10560
