Correct Answers
- Option – C
Let the first amount be ‘x’ and the second amount be ‘y’
(2/3)*x = (4/5)*y
=> x = 1.2y
Total interest earned in 2 years = 2070
or, (x*5*2)/100 + (y*9*2)/100 = 2070
or, (1.2y)*5 + (y*9) = 2070*100/2
or, 15y = 2070*200 => y = 6900
So, x = 1.2y = 69000*1.2 = 8280
Therefore, total sum invested = 6900+8280 = Rs.15180
2. Option- B
Let the sum invested by Shikha in the Scheme offering higher interest rate be ‘x’
So, Sum invested by Shikha in another scheme = (1500-x)
Thus, (x*6*2) /100 – [(1500-x)*4*2]/100 = 100
(12x/100) + (8x/100) – 120 = 100
On solving, x = Rs. 1100
Another amount = 1500 – 1100 = Rs. 400
Thus, the required ratio = 11 : 4
3. Option – C
Amount invested in Scheme-A = 17x
Amount invested in Scheme-B = 8x
Interest earned through Scheme-A = (17x)*(1+10/100)
2 – (17x) = (17x)*(0.21)
Interest earned through Scheme-B = (8x)*(21)*2/100 = (8x)*(0.42)
Therefore, required ratio = (17x)*(0.21) : (8x)*(0.42) = 17 : 16
4. Option- C
Let the money lent to James = Rs P
Then, money lent to Paul = Rs (10000 – P) [as total amount = Rs 10000]
SI for amount borrowed by James = (P x 15 x 2)/100 = 3P/10
SI for amount borrowed by Paul = {(10000 – P) x 18 x 2}/100 = 9/25 (10000 – P)
According to the given condition, (3P/10) – [(9/25) x (10000 – P)] = 360
=> (3P/10) – 3600 + 9P/25 = 360
=> 3P/10 + 9P/25 = 360 + 3600
=> 33P/50 = 3960
=> P = 3960 x 50/33
=> P = Rs. 6000
5. Option- D
Let, the principal amount be Rs. ‘P’
CI = P*[{1 + (12/200)}
1*2 – 1]
= P*[{1 + 6/100}
2 – 1]
= P*{(53/50)
2 – 1}
= P*{(2809 – 2500)/2500}
= (309/2500)*P
And,
SI = (P*12*1)/100
= (3/25)*P
Now, according to the question,
(309/2500)P – (3/25)P = 144
P*(9/2500) = 144
P = (144*2500)/9
= Rs. 40000
6. Option- D
Maturity amount from Scheme A = 5000*[1+(0.1)]
3 = 5000*(1.1)*(1.1)*(1.1) = Rs. 6655
Maturity amount from Scheme B = 5000+[5000*10*4/100] = Rs. 7000
Therefore, total maturity amount received by Raghav from the two schemes = 6655+7000 = Rs. 13655
7. Option – A
Annual interest income = 2880/4.5 = Rs. 640.
This implies an annual average rate of 8% per annum.
Thus 50% of Rs. 8000 is lent at 10%.
Income generated in 2 years by Rs. 4000 at 10% per annum = Rs. 800
8. Option- D
Let “R” be the rate of interest.
So according to question,
(9600*4*R)/100 + (16000*5*R)/100 = 9472
1184R = 9472
R = 9472/1184 = 8
9. Option- C
For the first person:
Amount earned after two years = 18000(1 + 10/100)
2 = Rs 21780
So, interest earned = 21780 – 18000 = Rs.3780
Interest earned at 5% p.a. for 3 years = 21780*5*3/100 = Rs 3267
Total interest earned = 3780 + 3267 = Rs.7047
For the second person:
Amount earned after two years at 10% compound interest = 22000(1 + 10/100)
2 = Rs.26620
Interest earned = 26620 – 22000 = Rs.4620
Interest earned at 5% p.a. for 3 years = 26620*5*3/100 = Rs.3993
Total interest earned = 4620 + 3993 = Rs.8613
Difference in the interest earned = 8613 – 7047 = Rs.1566
10.Option – C
Simple interest = p*n*r/100 = 25000*y*8/100 = 2000y.
So, amount after ‘y’ years = 25000+2000y.
Now, this amount is invested at 10% p.a compound interest for 2 years.
Amount obtained at compound interest = p*(1+(r/100))
n = (25000 + 2000y)*(1 + (10/100))
2= (25000 +
2000y)*1.1
2 = (25000 + 2000y)*1.21 = 30250 + 2420y
So, total interest = Amount – Principle = 30250 + 2420y – 25000 – 2000y = 420y + 5250
Now, simple interest obtained on Rs.13600 at 12.5% for ‘y+2’ years = 13600*12.5*(y+2)/100 = 1700y +
3400
According to question, 420y + 5250 = 1700y + 3400 – 1990
=> (1700 – 420) *y = – 3400 + 1990 + 5250 = 3840
=> 1280y = 3840
So, y = 3840/1280 = 3 years.
Therefore SI obtained on 25000 = 2000y=2000*3= Rs. 6000
