Suppose $250,000 is used to establish an annuity that earns 6%, compounded quarterly, and pays $6000 at the end of each quarter. It will take about 120 quarters until the account balance reaches $0.
Amount invested (Present value) = $250000
Quarterly payment (At the end of each quarter) (P) = $4500
Interest Rate (Quarterly) (r) = 6% /4
= 1.5% = 0.015
A number of quarters (n) = ?
Future value at the end = 0
Present value of Annuity formula:
Present value = P × 
250000 = 4500 × 
250000 = 300000 × 
250000 / 300000 = 
0.83333 = 
n = 120
Hence is shall take 120 Quarters until the account balance is $0.

Answer: c. A bilateral contract
Explanation:
In a bilateral contract, the parties involved promise to both perform duties to the other which will make them both an obligor and an obligee.
An obligor is one who owes a duty to another and the obligee is one who a duty is owed to.

Answer:
B
Explanation:
Real GDP measure total economic output by an economy in a specific geographical boundary regardless of ownership of factors of production, within a year, ceteris paribus.
Real GDP is a good indicator but is not a perfect indicator as underground economy (private tuition whereby taxes and consumption of goods and services) are not accounted for.
Real GDP does not measure Non-Material standard of living like leisure hours, health and life expectancy... It needs other indicators.
Both B and D is a bit effy as:
For D, GDP does not even measure such Non-Material SOL
For B, GDP is not 100 percent accurate on measuring household production (local production? I believe there is no such phrasing as household production as by economics, household is involved in household spending, Contributing to Consumption expenditure in Aggregate Demand.) as there are other factors like presence of underground economy that is not accounted for.
However, B seems like the most accurate ans as it still measures national output.
