Correct Answers
 Option – C 5 yr
 Option A
Let p be the principal.
p (20 * 3)/100 = Rs.1800/
p = Rs.1800 * 5/3 = Rs.3000/.
Therefore the compound interest accrued in two years
= Rs.3000((1+20/100)^{2} – 1)
= Rs.3000 (1.44 – 1) = Rs.1320/
 Option E
Let the amount invested by Ramesh is Rs P.
Hence according to the question, 1.1(1.1P – 400) = 550
=> 1.1P – 400 = 500
=> 1.1P = 900
P = 818.20= 820( Approx)
 Option B
Let ‘p’ be the sum of money.
Given that,
p * (16) * 3/100 – p * (12) * 3/100 = Rs.1440/
12p/(100) = Rs.1440/
p = Rs.(1440 * 100)/12
p = 12000/
 OptionB
Let’s assume that the required time = T years
Hence in 2
nd case, (6336 – 4800) = (4800´8´T)/100
=> T = (1536´100)/(4800´8)
=> T = 4 years
Let’s suppose that the principal amount be Rs P in 1
st case.
Hence, P + (P´((5´4)/100)) = 7200
=> 1.2P = 7200
P = 6000
 Option B
We know that, A = P (1+R/100)T
Rs. 27,783 = Rs. 24,000 (1+5/100)T
27,783/24,000 = (1+0.05)T
1.157625 = (1.05)T
(1.05)
3 = (1.05)T
T = 3 years
 Option – C
Let P is the principal amount and R is the interest rate
Let the simple interest on the principal for 3 years be ‘x’ and for 7 years it will be ‘y’
x = P*R*3/100 and y = P*R*7/100
=> y = (7/3)x
Now, P+x = 17472 ………(i)
P+y = 21356
or, P+(7/3)x = 21356 ………(ii)
Operate [(7/3)*Eq.(i) – Eq.(ii)]
(7/3)*P + (7/3)*x – P – (7/3)x = (7/3)*17472 – 21356
or, 4P/3 = 19412
or, P = 14559
Hence, option c
Alternate solution
According to the question, it is given that,
P + (P * R * 3)/100 = 17472
or, P (1 + 3R/100) = 17472 …….(i)
and P + (P * R * 7)/100 = 21356
or, P (1 + 7R/100) = 21356 ……(ii)
Equation (ii) – (i) we get,
4PR/100 = 3884
or, P [3R/100] = 3/4 (3884)
or, P [3R/100] = 2913……….(iii)
Putting the value of equation (iii) in equation (i) we get,
P + 2913 = 17472
or, P = Rs. 14559
 Option A
Let the money invested by Mr. Raghunathan in Stock P be P
Therefore, Money invested in Stock Q = Rs.(35000 –P)
Now, according to the question,
Return received from Stock P = 3600
=> (P *12*2)/100 = 3600
=> P = (3600*100)/12*2 = Rs.15000
Now, Money invested in Stock Q = Rs.(35000 – 15000) = Rs.20000
Therefore, return received from Company Q = 20000*[{1 + (10/100)}
2 – 1]
= 20000*{(121 – 100)/100}
= Rs. 4200
 Option – D
The difference between the simple interest for 2 years and compound interest for 2 years is the interest on
the first year’s simple interest.
S.I. for two years = 4000
So, S.I. for one year = 4000/2 = Rs. 2000
C.I. for 2 years – S.I. for 2 years = 4080 – 4000 = Rs. 80 = Interest on the first year’s S.I.
Interest on Rs. 2000 for 1 year = Rs. 80
Or, [2000*(Rate of interest)*(1)]/100 = 80
or, Rate of interest = 4%
Let the sum be P
S.I. on P in two years = Rs. 4000
or, (P*4*2)/100 = 4000
or, P = Rs. 50000
 Option – B
Let the amount invested in the scheme returning compound interest = P
Let the amount invested in the scheme returning simple interest = Q
According to question,
P*[(1+0.1)
2
– 1] = Q*(0.1)*4
=> P*(1.21 – 1) = Q*(0.4)
=> P/Q = (0.4)/(0.21) = 40:21
