Compound interest:
Interest = Amount – Principal
If Rs. ‘P’ is invested at a rate of ‘r%’ p.a. compounded annually for ‘t’ years, then the amount received after ‘t’ years will be = P × {1 + (r/100)}t
If the interest is not compounded annually, then
Effective rate of interest = Actual rate ÷ Number of times the interest is compounded in a year
Effective time period = Actual time period × Number of times the interest is compounded in a year

Simple interest:
If Rs. ‘P’ is invested at simple interest of ‘r%’ p.a. for ‘t’ years, then the amount received after ‘t’ years will be = P + {(P × r × t)/100}
And, the simple interest received = {(P × r × t)/100}
Relationship between simple interest (SI) and compound interest (CI):
When a principal (P) is invested at the rate of ‘r%’ p.a., then
Difference between SI and CI after two years = P × (r/100)2
Difference between SI and CI after three years = P × (r/100)2 × {(r/100) + 3}

Solution 1: A)
Let the amount invested by Ramesh be Rs. ‘x’
Amount received by him after 2 years of CI = x × (1 + 0.12)2 = Rs. 1.2544x
Amount received by him after 7 years = 1.2544x + 1.2544x × 5 × 0.10 = 1.2544x + 0.6272x = Rs. 1.8816x
So, interest earned after 7 years = 1.8816x – x = 6612
0.8816x = 6612, x = 7500
So, the amount invested by Ramesh = Rs. 7,500
Hence, option a.
Solution 2: A)
Interest earned by Pooja = 10000 × {(1 + 0.20)3 – 1} = Rs. 7,280
Interest earned by Rohit = 12000 × {(1 + 0.25)2 – 1} = Rs. 6,750
So, the desired difference = 7280 – 6750 = Rs. 530
Hence, option a.
Solution 3: A)
Interest earned by Varun = x × {(1 + 0.10)3 – 1} = Rs. 0.331x
Interest earned by Karan = (x + 3000) × {(1 + 0.12)2 – 1} = Rs. (0.2544x + 763.20)
According to question: 0.2544x + 763.20 – 0.331x = 227
0.0766x = 536.20
x = 7000
So, the value of x = Rs. 7000
Hence, option a.

Solution 4: A)
Interest earned by Amit = 25000 × {(1 + 0.12)2 – 1} = Rs. 6,360
Interest earned by Rajeev = 20000 × {(1 + 0.15)2 – 1} = Rs. 6,450
So, the desired difference = 6450 – 6360 = Rs. 90
Hence, option a.
Solution 5: B)
Let the amount deposited in scheme B be Rs. ‘x’.
So, amount deposited in scheme A = Rs. (24000 – x)
According to question,
(24000 – x) × 0.24 – x{(1.2)2 – 1} = 660
5760 – 0.24x – 0.44x = 660
0.68x = 5100
x = 7500
So, the amount deposited in scheme B = Rs. 7500
Hence, option b.
Solution 6: A)
According to the question,
(x × 24 × 4)/100 = (x – 130)
Or, 24x = 25x – 3250
Or, x = Rs. 3250
Therefore, interest received at compound interest
= (x + 250)(1 + 20/100)2 – (x+ 250) = 3500(1.2)2 – 3500 = Rs. 1540
For I:
{(x/2) – 85} = {3250/2 – 85} = (1625 – 85) = Rs. 1540
Therefore, I can be the answer.
For II:
{(x /5) + 860} = {(3250/5) + 860} = (650 + 860) = Rs. 1510
Therefore, II cannot be the answer.
For III:
(2x – 4980) = (2 × 3250 – 4980) = Rs. 1520
Therefore, III cannot be the answer.
Hence, option a.

Solution 7: D)
According to the question,
(x × 20 × 2)/100 + x(1 + 20/100)2 – x = 1260
Or, 2x/5 + 0.44x = 1260
Or, 2x + 2.2x = 6300
Or, x = 6300/4.2 = Rs. 1500
Amount received at simple interest = 2x/5 + x = Rs. 2100
For I:
(2x – 900) = (2 × 1500 – 900) = Rs. 2100
Therefore, I can be the answer.
For II:
{(x/2) + 1350} = {(1500/2) + 1350} = Rs. 2100
Therefore, II can be the answer.
For III:
(x + 700) = 1500 + 700 = Rs. 2200
Therefore, III cannot be the answer.
Hence, option d.
Solution 8: D)
3750 = x × 15% × 2
x = Rs. 12500
Sum = Rs. 18000
Amount after two years at compound interest = 18000 × 110% × 115%
= Rs. 22770
Compound interest earned = 22770 – 18000 = Rs. 4770
Hence, option d.
SBI Clerk Mains Free Mock Test
Solution 9: B)
Simple interest = 14000 × 2 × R%
2000 = 140 × 2 × R
R = 50/7%
Rate of compound interest = 50/7 + 20/7 = 10%
Principal = 14000 + 2000 = Rs. 16000
Compound interest = 16000 × (1 + 10/100)2 – 16000
= 16000 × 121/100 – 16000 = Rs. 3360
Hence, option b.
Solution 10: A)
According to question;
7250 × R/100 × 3 + 7500 × (R + 12)/100 × 3 = 8010
72.5R + 75R = 8010/3 – 75 × 12
Or, 147.5R = 1770
Or, R = 12
Desired answer = [(1.15)2 – 1] × 8000 = Rs. 2580
Hence, option a.
