Q:

The difference between Simple Interest and Compound Interest at the rate of 12% on the same amount for 3 years is Rs. 112.32. What is the principal amount if interest is compounded annually?

A) Rs. 25000 B) Rs. 2500
C) Rs. 50000 D) Rs. 5000
 
Answer & Explanation Answer: B) Rs. 2500

Explanation:

Let the principal amount be Rs. x
Calculating SI:
SI for 1 year at 12% rate is Rs (12/100)*x. For 3 years it will be Rs (36/100)*x ------ (1)
Calculating CI:
For 1st year, Interest = (12/100)*x
For 2nd year, interest = (12/100)*x + (12/100)*x + (144/10000)*x
For 3rd year, interest = (12/100)*x + (12/100)*x + (12/100)*x + (144/10000)*x + (144/10000)*x + (1728/1000000)*x. ------ (2)
Subtracting equation 2 and 1 and solving further,
312*144*x/1000000 = 112.32
X = Rs 2500.
Alternative way: Using formula for Difference
between CI and SI for 3 years

we can also use the above formula to find the value of P.

What stops one branch of government from becoming too powerful?

A) State governments B) Every 4 years of President election
C) Members of congress D) Checks and Balances
 
Answer & Explanation Answer: D) Checks and Balances

Explanation:

A procedure or method called Checks and Balances stops one branch of government from becoming too powerful.

  • In the United States, there are three branches of government: The Executive, Legislative, and Judicial.

 

  • Each has its own responsibilities and at the same time they work together to make the country run smoothly and to assure that the rights of citizens are not ignored or disallowed.

 

  • There is a clear separation of powers between them.

 

  • Checks and Balances limit the power within each branch.

 

  • Each branch can stop and/or override processes within other branches in manners that are outlined in federal laws, regulations, and the constitution.

 

  • This way, their powers are balanced because the branches of government have the responsibility to check each other.
