In an electronic accounting system, transaction data undergoes sequential stages during the data processing cycle. Arrange the following key stages of the accounting data processing cycle in the correct chronological order from start to finish.

At the end of an accounting period, a sole trader reported a Gross Profit of $\text{N}180,000$ and received discounts totaling $\text{N}2,500$. A review of the business transactions and adjustments reveals the following:

- Rent paid of $\text{N}24,000$ included $\text{N}4,000$ paid in advance for the next period.
- Accrued electricity charges at year-end amounted to $\text{N}3,000$.
- The provision for doubtful debts is to be increased from $\text{N}5,000$ to $\text{N}7,000$.
- A new office computer purchased on credit for $\text{N}10,000$ was erroneously recorded in the general office expenses account.

Based on the information above, what is the correct Net Profit for the year?

Major commercial flour milling plants in Nigeria are overwhelmingly concentrated at seaport terminals such as Lagos and Port Harcourt rather than near inland agricultural hinterlands. According to Alfred Weber's industrial location theory, which factor primarily accounts for this spatial pattern?

Kofi, a fashion designer, maintains incomplete accounting records. On 1 January 2025, his total assets were ₦450,000 and total liabilities were ₦150,000. On 31 December 2025, his total assets were ₦780,000 and total liabilities were ₦220,000.

If $50\text{ cm}^3$ of sulfur dioxide ($SO_2$) gas diffuses through a porous partition in $20\text{ seconds}$, and the same volume of an unknown hydrocarbon gas $Z$ diffuses under identical conditions of temperature and pressure in $10\text{ seconds}$, what is the molar mass of gas $Z$ in $\text{g/mol}$? (Relative atomic masses: $\text{S} = 32$, $\text{O} = 16$)

A solar observation station located at longitude $23^\circ\text{W}$ records local solar noon ($12:00\text{ PM}$) at a specific instant. At that exact moment, a research vessel at sea notes its local solar time as $7:16\text{ PM}$ ($19:16$) on the same day. What is the longitude of the research vessel in degrees East?

Which of the following landforms is formed by glacial deposition and is characterized as an elongated, streamlined, teardrop-shaped hill of unsorted till with its blunt end pointing towards the direction of ice advance?

A progressive transverse wave traveling through a primary medium is governed by the mathematical wave equation $y = 0.05 \sin\left(100\pi t - 2.5\pi x\right)$, where $x$ and $y$ are measured in meters and $t$ is in seconds. Upon entering a secondary medium, the wave undergoes refraction such that its wavelength decreases by $20\%$. What is the speed of the wave in the secondary medium in $\text{m/s}$?
