Solution:
QUESTION: 3

The Simple interest on a certain sum for 2 years at 20% per annum is Rs. 80. The corresponding compound interest is 

Solution:

P = (100×80)/(20×2) = 200
20%(200)= 40
20%(40) = 8
Required compound interest = 2(40)+ 8
= 88

QUESTION: 7

A sum amounts to Rs. 882 in 2 years at 5% compound interest. The sum is 
Solution:

Compound interest = Amount -Principal
Amount = P(1 + R/100)N 
882 = P(1+5/100)2
=  882 × 20/21 × 20/21 
P = 800
 

QUESTION: 8

Simple interest on a certain sum of money for 4 years at 5% per annum is half the compound interest on Rs. 3000 for 2 years at 10% per annum. The sum placed on simple interest is: 
Solution:

C.I = P[(1 + r/100)n - 1]
C.I = 3000[(1 + 0.10)2 - 1]
= 3000(1.21 - 1)
⇒ 3000 * 0.21 
⇒ 630
S.I = 630/2
⇒ 315
As we know that, P = (SI * 100)/(R * T)
⇒ (315 * 100)/(4 * 5)
⇒ 1575

QUESTION: 9

The least number of complete years in which a sum of money put out at 20% compound interest will be more than doubled is
Solution:

P [1 + (r/100)]n  >  2P
⇒ P [1 + (20/100)]n  >  2P
[1 + (2/10) ]n  > 2
[12 / 10]n  > 2
[6/5]n  > 2
{6/5 * 6/5 * 6/5 * 6/5}  >  2
∴ n = 4
