Sample ENA Section Enquêtes Économiques Practice Questions

Try these sample questions to review concepts for the ENA Section Enquêtes Économiques exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 25+ question experience with AI tutoring.

1Under Senegal's law on prices and consumer protection, what is the relationship between free prices and regulated prices?
A.Every seller must obtain individual approval for every price
B.Prices are generally determined by competition, with regulation permitted under the law's conditions
C.All products must use the same retail margin
D.Price regulation applies only if every seller agrees
Explanation: The law starts from prices determined by competition and permits regulation when the prescribed circumstances and procedures apply. An investigator must therefore establish whether the particular product and transaction fall under a valid regulatory measure.
2For this exercise, a valid order permits a maximum retail margin of 10% of the verified acquisition cost of 20,000 FCFA per unit. No additional charge is permitted. A trader sells 30 units at 23,000 FCFA each. What is the total amount charged above the ceiling?
A.90,000 FCFA
B.60,000 FCFA
C.30,000 FCFA
D.3,000 FCFA
Explanation: The permitted unit price is 20,000 × 1.10 = 22,000 FCFA. The excess is 1,000 FCFA per unit, so 30 units produce a total excess of 30,000 FCFA; the supplied order is hypothetical, not a claimed current commodity tariff.
3Why must a seller communicate prices and relevant sale conditions to consumers?
A.To replace the need to describe the product
B.To make every product subject to an administered price
C.To transfer all contractual risk to the consumer
D.To allow an informed decision before entering the transaction
Explanation: The law requires commercial information through marking, labelling, display or another appropriate method. Price information works with information about essential characteristics and conditions; one does not replace the others.
4An applicable order fixes a retail ceiling of 5,000 FCFA. A trader charges 5,400 FCFA and calls the extra 400 FCFA a compulsory handling fee, although the order allows no such addition. What is the strongest assessment?
A.The compulsory addition can make the actual price exceed the lawful ceiling
B.Renaming part of the price always removes it from price control
C.Only the amount printed beside the word 'price' can be examined
D.The buyer's payment automatically legalizes any excess
Explanation: An investigation should examine the substance of the amount compulsorily charged and the applicable order. A trader cannot necessarily avoid a ceiling by relabelling an unavoidable part of the purchase price.
5An operator obtains approval of a price structure using overstated freight documents. Later the actual freight falls, but the operator maintains the old cost element where the applicable pricing rules require adjustment. Which investigation addresses both concerns?
A.Check only whether the approval document bears a stamp
B.Examine only the operator's market share
C.Verify the underlying cost evidence and the continued lawfulness of the price structure
D.Treat an approved price as immune from examination regardless of the information supplied
Explanation: The law identifies prices obtained through false information and retention of reduced cost elements used in an approved structure as potential illicit-price situations. An approval document does not make its underlying evidence or later application immune from investigation.
6To test a regulated margin based on acquisition cost, which evidence is most directly useful?
A.The shop's target margin without supporting cost records
B.The relevant purchase invoices and documents supporting allowable cost adjustments
C.A competitor's retail price without evidence of the trader's cost base
D.The trader's advertised selling price without purchase records
Explanation: A cost-based ceiling must be tested against the transaction's verified cost base and the applicable order. Invoices and supporting adjustments connect the evidence to the calculation more directly than a target profit figure.
7A seller's scale displays one kilogram when a verified test mass of 900 grams is placed on it. Which issue should market surveillance examine?
A.Whether the posted unit price alone proves quantity compliance
B.Whether the seller can substitute the scale's display for independent verification
C.Whether a supplier's invoice alone establishes the shop scale's accuracy
D.Measurement accuracy and the risk that consumers receive less than the stated quantity
Explanation: An inaccurate measuring instrument can misrepresent the quantity supplied and undermine transaction fairness. The investigator should verify the instrument and applicable metrology requirements rather than infer compliance from price alone.
8What is the subject of Loi n° 2021-25 sur les prix et la protection du consommateur?
A.Only competition agreements between enterprises, excluding consumer contracts
B.Only product safety, excluding price and invoice rules
C.Commercial transparency, price rules and relations between consumers and suppliers
D.Only customs duties on imported consumer goods
Explanation: The law regulates commercial practices and prices to promote transparent and fair transactions, and addresses consumer-supplier relations. It is therefore a central source for these selected economic-investigation topics.
9When should a professional supplier make the essential characteristics of a product or service clear and comprehensible to a consumer?
A.Before conclusion of the contract
B.Only after the consumer complains
C.Only after the warranty expires
D.Only if a court has already found a defect
Explanation: The information duty operates before contract formation so that the consumer can make an informed choice. Later complaint handling does not replace that pre-contractual duty.
10What is the central statutory test for an abusive clause in a consumer contract?
A.Whether the contract is longer than one page
B.Whether the supplier uses standard terms
C.Whether the consumer negotiated the delivery date
D.Whether the clause creates a significant imbalance in rights and obligations to the consumer's detriment
Explanation: The law focuses on a significant imbalance detrimental to the consumer or non-professional. Standard wording or contract length alone does not establish that test; context and the other contractual terms matter.
