Solutions for SBI Clerk Simple Interest and Compound Interest Questions PDF:

Solutions:

S.I = PRT/100 = (1000×20×4)/100= Rs. 800

Let the sum be Rs. x,
Amount = Rs. 10x/9 , T= 1 year
S I = (Amount – sum) = Rs. (10x/9-x) = Rs. (x/9) R = ((100×SI)/(P×T))=(100×x/9×1/x)%per annum = (100/9)% per annum = 11 1/9% per annum

For borrowed money P = Rs. 2000, R = 5% per annum and T = 5/2 year
SI = Rs. (2000×5/2×5×1/100)= Rs. 250
For lent money P = Rs. 2000, R = 6% per annum and T = 5/2 year
SI= Rs. (2000×5/2×6×1/100) = Rs. 300
His profit = Rs. (300 – 250) = Rs. 50

Interest = (Principal * interest * No. of years )
Interest = (30,000*3*5)/100
Interest = 4,500
x% of 22,500 = 4,500
x = (4500/22,500)*100
x = 20

Simple interest = Principal * no. of years * rate of interest = 10,000*2*.03=600
Let his salary be x
.03x=600
x=20,000

Let the rate of interest on the principal be R.
So, 19800*R*3/100 = 7128
So, R = 12%
Hence, the compound interest on the same amount for the same time period equals
19800*1.12^3 – 19800 = 27817.57 – 19800 = Rs. 8017.57

Let the original amount invested be x.
Hence, the amount with him after recieving the dividend is 1.3x.
Now, this amount was reinvested in ratio 6:7 in debt and equity funds. Amount invested in equity fund was 94,500
Hence, (0.7x/1.3)=94,500, x=175500
now, the original amount invested in equity was (5/9)*175500=97,500

We can calculate the compound interest as follows
Compound Interest = 6300 x 1.05 x1.05 = 6945.75

Let N be total number of sweets and each student get x sweet.
N/200 = x, N=200x
Also, as per given condition,
N/160 = x+2
N = 160x + 320
200x = 160x + 320
40x = 320
x = 8
Number of sweets = 1600
Hence, the correct option is option D.
