When compound interest is applied, interest

is paid on both the original principal and on earned interest. If you make a

deposit into a bank account that pays compounded interest, you will receive

interest payments on the original amount that you deposited,

is paid on both the original principal and on earned interest. If you make a

deposit into a bank account that pays compounded interest, you will receive

interest payments on the original amount that you deposited,

as well as

additional interest payments. This allows your investment to grow even more

than if you were paid only simple interest.

**Answers with Explanation:**

**1.**

(2) Since,

CI/SI = (200+R)/200

3052.8/2880

= (1+R/200)

= (1+R/200)

R = 12%

**2.**

(1) 4.24

x 100000 = x/ (1+r/100) + x / (1+r/100)^2

=

x/(1+12/100) + x/(1+12/100)^2

x/(1+12/100) + x/(1+12/100)^2

=

25x/28 + 25

25x/28 + 25

^{2}x/28^{2}= 1325x/784**X =**

250880

250880

**3.**

(2) Let

annual payment 100 Rs.

100

+(100+R) + (100 +2*R) + (100 +3*R) = 15260

+(100+R) + (100 +2*R) + (100 +3*R) = 15260

100+

106 + 112 + 118 = 15260

106 + 112 + 118 = 15260

436 =

15260

15260

100 =

15260×100 / 436 = 3500

15260×100 / 436 = 3500

**4.**

(1) P

= 6000

For 1sr

year CI = 5% of 6000 = 300

year CI = 5% of 6000 = 300

Amount

= 6000 + 300 = 6300

= 6000 + 300 = 6300

P for 2

year = 63000 â€“ 2100 = 4200

^{nd}year = 63000 â€“ 2100 = 4200

CI for

2

2

^{nd}year = 5% of 4200 = 210
Amount

2

2

^{nd}year = 4200 + 210 = 4410
P for 3

year = 4410 â€“ 2100 = 2310

^{rd}year = 4410 â€“ 2100 = 2310

CI for

3

3

^{rd}year = 5% of 2310 = 115.5
Required

amount = 2310 + 115.5 = 2425.5

amount = 2310 + 115.5 = 2425.5

**5.**

(3) Since

difference = PR

^{2}(300+R)

31 = Px10

(300+10)/ 100

^{2}(300+10)/ 100

^{3}

P =
