Ten JAMB 2025 questions with answers

1. From the Mathematics paper

   1.

   Which of the following angles cannot be constructed using a protractor, a compass, and a sharpened pencil?

   1. A
      41¼°
   2. B
      26⅔°
      Correct
   3. C
      22½°
   4. D
      33¾°
   Show answerHide answer

   Answer: B

   Look carefully at the instruments you are given. A protractor is marked in whole degrees, so it can lay off any whole number of degrees. A pair of compasses adds only one extra power: it can bisect an angle, and you may bisect again and again.

   So every angle you can produce with this set must be a whole number of degrees, or a half, a quarter, an eighth of a whole number of degrees — never a third.

2. From the Physics paper

   2.

   What colour has the lowest frequency in the spectrum of white light?

   1. A
      Red
      Correct
   2. B
      Yellow
   3. C
      Violet
   4. D
      Blue
   Show answerHide answer

   Answer: A

   When white light passes through a prism, it splits into the familiar band of colours: red, orange, yellow, green, blue, indigo, violet (ROYGBIV).

   Since the speed of light in a given medium is constant, frequency and wavelength are inversely related. Red light has the longest wavelength in the visible spectrum, which means it has the lowest frequency.

   So the colour with the lowest frequency in the spectrum of white light is red.

3. From the Chemistry paper

   3.

   Commercial deodorant is an example of a colloid called

   1. A
      Gel
   2. B
      Foam
   3. C
      Aerosol
      Correct
   4. D
      Emulsion
   Show answerHide answer

   Answer: C

   A colloid is classified by the physical states of its two phases: the dispersed phase (the substance spread out) and the dispersion medium (the substance it is spread through).

   A commercial deodorant, like an insecticide or hair spray, is packaged so that it releases fine liquid droplets dispersed in a gas. This liquid-in-gas colloid is called an aerosol, and it is correct here.

4. From the Biology paper

   4.

   When calyx of a flower is joined together, it is called

   1. A
      Gamosepalous
      Correct
   2. B
      Polysepalous
   3. C
      Polypetalous
   4. D
      Gamopetalous
   Show answerHide answer

   Answer: A

   The calyx is made up of the sepals of a flower. When the sepals are fused together into one unit, this condition is called gamosepalous.

   If the sepals are separate and not joined, the calyx is described as polysepalous instead — the opposite condition, and a common mix-up.

5. From the Government paper

   5.

   Before the 1976 reforms, local government administration in Nigeria was characterised by

   1. A
      direct election of council chairmen by the electorate
   2. B
      a uniform single-tier structure applied throughout the federation
   3. C
      full financial autonomy from the regional governments
   4. D
      diversity of structures, with each region running its own separate system
      Correct
   Show answerHide answer

   Answer: D

   Answer: local government before the 1976 reforms was marked by diversity of structures, with each region running its own separate system.

6. From the Literature in English paper

   6.From the novel;

   The experience of the persona in Eliot's "The Journey of the Magi" is

   1. A
      A leisurely and comfortable royal excursion free of hardship
   2. B
      A brief errand quickly forgotten once the persona returns home
   3. C
      A physically gruelling journey that ends in spiritual disillusionment and alienation
      Correct
   4. D
      A triumphant military conquest celebrated by the persona's own people
   Show answerHide answer

   Answer: C

   In "The Journey of the Magi," the persona (one of the Magi) narrates a dramatic monologue looking back on the trip to Bethlehem. The journey itself is described as harsh: "A cold coming we had of it, / Just the worst time of the year," with sick camels, unfriendly towns, and voices whispering that the whole thing was "folly." This rules out any option describing the trip as comfortable or leisurely.

   So the physically gruelling journey followed by spiritual disillusionment and alienation is correct. A comfortable excursion contradicts the poem's opening hardship; a military conquest misreads the peaceful pilgrimage entirely; and a "quickly forgotten" trip ignores the persona's lasting unease at the poem's end.

7. From the Economics paper

   7.

   A firm will shut down in the long run if its earning is

   1. A
      greater than average fixed cost
   2. B
      less than average variable cost
   3. C
      equal to average revenue
   4. D
      less than average total cost
      Correct
   Show answerHide answer

   Answer: D

   In the long run, all costs are variable — a firm has time to sell its plant, end its lease, and completely leave the industry. Because of this, a firm will shut down permanently if its earning (average revenue) is less than its average total cost, meaning it is not even covering the full cost of staying in business, both fixed and variable costs together.

   So the correct completion is: a firm will shut down in the long run if its earning is less than average total cost.

8. From the Christian Religious Studies paper

   How many plagues did God send on Egypt?

   1. A
      Ten
      Correct
   2. B
      Nine
   3. C
      Seven
   4. D
      Twelve
   Show answerHide answer

   Answer: A

   God sent ten plagues upon Egypt to compel Pharaoh to release the Israelites (Exodus 7-12). They were: water turned to blood, frogs, lice/gnats, flies, livestock disease, boils, hail, locusts, darkness, and the death of the firstborn. The tenth plague finally moved Pharaoh to let the people go.

9. From the Commerce paper

   9.

   Musa entered into a contract to supply two cows to Aro. Before the agreed date of supply and without the knowledge of the two
   parties, thieves stole the cows. This is an example of termination of contract by

   1. A
      Frustration
      Correct
   2. B
      Breach of contract
   3. C
      Lapse of time
   4. D
      Mutual agreement
   Show answerHide answer

   Answer: A

   Frustration occurs when an unforeseen event beyond the control of both parties makes contract performance impossible. The theft of the cows before delivery, unknown to both parties, frustrates the contract and automatically discharges both parties from their obligations.

10. From the Principles of Accounts paper

    10.

    Suspense account is used in the correction of

    1. A
       compensating errors in the ledger accounts
    2. B
       errors of principle in the ledger accounts
    3. C
       errors that affect the agreement of the trial balance
       Correct
    4. D
       errors of complete omission from the books
    Show answerHide answer

    Answer: C

    A suspense account is only opened when the trial balance refuses to balance. The bookkeeper takes the difference between the debit and credit totals and parks it in a suspense account so that the trial balance agrees for the time being. When the errors are later traced, the correcting journal entries are passed through the suspense account, and once every one of them has been cleared the suspense account closes itself — its balance becomes nil. So the correct answer is errors that affect the agreement of the trial balance.
