Fiverr · Fee Structure
On a $200 Fiverr order, how much does the freelancer receive, and what service fee does the client pay?
Correct Answer — C Freelancer receives $160; client pays 5.5% ($11) service fee.

Fiverr operates a dual fee structure — it collects from both parties in a transaction.

Freelancer (seller) fee: 20%. On $200 → Fiverr takes $40 → freelancer receives $160.
Client (buyer) fee: 5.5% of the order value for orders above $50. On $200 → client pays an extra $11, totalling $211.
An additional $2 small order fee applies only to orders under $50 — not applicable here.
Fiverr acts as an escrow service, holding payment securely until delivery is confirmed.
Exam tip: Always distinguish the 20% seller fee from the 5.5% buyer fee. The $2 small order fee is a common distractor — it only applies sub-$50.

Dropshipping · Business Model
In a dropshipping business (AliExpress supplier, eBay storefront), who ships the product, and what is the profit on a LKR 5,000 sale costing LKR 3,500 from the supplier?
Correct Answer — B AliExpress ships directly to the customer; profit is LKR 1,500 before fees.

Dropshipping's defining feature is that the retailer never handles or ships the product.

1
Customer places order on the eBay store (LKR 5,000).
2
Retailer forwards the order and customer's shipping address to the AliExpress supplier.
3
AliExpress supplier ships directly to the customer (LKR 3,500 cost).
4
Gross profit = LKR 5,000 − LKR 3,500 = LKR 1,500 (before eBay/PayPal fees).
+
Advantages: Low startup cost, no inventory risk, location-independent, easy scalability.
Disadvantages: Lower margins (retail pricing, no bulk discount), no quality control, dependency on supplier, longer shipping times.

Google AdSense vs AdMob
A blogger and a mobile app developer both want to monetise with Google ads. Which platform suits each, and what revenue share do they retain?
Correct Answer — B Blogger → AdSense (68%); App developer → AdMob (60%).
Google AdSense — for websites and blogs. Publishers retain 68% of ad revenue. Formats: display, text, video ads.
Google AdMob — for mobile apps. Developers retain 60% of ad revenue. Formats: banner, interstitial, rewarded ads.
Shared advantages: Easy integration, large advertiser network, advanced targeting, multiple ad formats.
Shared risks: Revenue volatility, strict policy enforcement (account suspension), limited control over ad content, potential ad-blocking by users.
Memory aid: AdSense = Site (S→S). AdMob = Mobile (Mob = Mobile). Revenue: AdSense 68% > AdMob 60%.

Affiliate Marketing · Mechanism
How does an affiliate (e.g. a YouTuber with an AliExpress affiliate link) earn money, and what are the key risks of this model?
Correct Answer — B Commission earned only on completed sales via unique link; risks include commission-only income and merchant dependency.

Affiliate marketing is performance-based — earnings depend entirely on successful referrals, not clicks or views alone.

Mechanism: Affiliate promotes a product using a unique tracking link. A commission is paid only when a sale/lead is completed through that link.
Popular platforms: Amazon Associates, eBay Partner Network, AliExpress Affiliate (up to 9% commission, 150M+ products, 200+ countries).
+
Advantages: Passive income potential, no product/inventory management, flexible and scalable, targeted niche marketing.
Risks: Commission-only (zero income if no conversions), merchant dependency (fulfilment failures hurt your reputation), market saturation, payment delays.

Cryptocurrency · Mining vs Staking
Compare cryptocurrency mining and staking: what consensus mechanism does each use, and what is the primary resource required?
Correct Answer — C Mining = PoW (hardware + energy); Staking = PoS (locked digital assets).
Mining (Proof-of-Work / PoW): Miners solve complex mathematical puzzles using specialised hardware (GPUs, ASICs) to validate transactions and earn newly minted coins. High energy consumption; highly competitive — often requires joining mining pools.
🔒
Staking (Proof-of-Stake / PoS): Participants lock (stake) existing coins in a compatible wallet to validate transactions and earn rewards. Far more energy-efficient than PoW.
Other earning methods: Trading (exploit price fluctuations, use exchanges like Binance/Coinbase/Kraken/Bybit/Crypto.com) and Investing (long-term holding based on growth potential).
Key cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), Tether (USDT), BNB, USD Coin (USDC), and many others.
Summary table:   Mining → PoW → Hardware & Energy → Competitive.  |  Staking → PoS → Held coins → Efficient.
