**Solutions forÂ SBI Clerk Simple Interest and Compound Interest Questions PDF:**

**Solutions:**

**1) Answer (C)**

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

**2) Answer (B)**

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 = ((100Ã—SI)/(PÃ—T))=(100Ã—x/9Ã—1/x)%per annum = (100/9)% per annum = 11 1/9% per annum

**3) Answer (C)**

For borrowed money P = Rs. 2000, R = 5% per annum and T = 5/2 year

SI = Rs. (2000Ã—5/2Ã—5Ã—1/100)= Rs. 250

For lent money P = Rs. 2000, R = 6% per annum and T = 5/2 year

SI= Rs. (2000Ã—5/2Ã—6Ã—1/100) = Rs. 300

His profit = Rs. (300 – 250) = Rs. 50

**4) Answer (C)**

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

**5) Answer (C)**

Simple interest = Principal * no. of years * rate of interest = 10,000*2*.03=600

Let his salary be x

.03x=600

x=20,000

**6) Answer (B)**

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

**7) Answer (E)**

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

**8) Answer (A)**

We can calculate the compound interest as follows

Compound Interest =Â 6300 x 1.05 x1.05 = 6945.75

**9) Answer (E)**

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.

**10) Answer (A)**

Compound Interest Acrrued = 12000*(1.12)^3 -12000 = 16859.14 – 12000 = 4859.136

Siimple Interest acrrued = 12000*3*0.12 = 4320

Difference between Compound Interestand Simple interest = 4859.136 – 4320 = 539.136

Therefore, the correct option is option A.
