   (1 mark)

   Marking scheme

   A. Ksh 2,000

   B. Ksh 480

   C. Ksh 1,920

   D. Ksh 2,880

   (1 mark)

   Marking scheme

   A. Ksh $2,000$ — the selling price is $120\%$ of the buying price, so work backwards: $2,400÷1.2=2,000$. C takes $20\%$ off the selling price instead, which is not the same thing.

10. Question 10

    1 mark

    A. Ksh 3,750

    B. Ksh 10,000

    C. Ksh 12,000

    D. Ksh 11,250

    (1 mark)

    Marking scheme

    D. Ksh $11,250$ — the reduction is $25\%$ of $15,000=3,750$, so the sale price is $15,000-3,750=11,250$. A gives the reduction rather than the price paid.

14. Question 14

    1 mark

    Ouma borrowed Ksh 20,000 at 5% simple interest for 3 years. How much will he repay?

    A. Ksh 25,000

    B. Ksh 21,000

    C. Ksh 30,000

    D. Ksh 23,000

    (1 mark)

    Marking scheme

    D. Ksh $23,000$ — the question asks what he repays, which is the loan plus the interest. Interest is $\frac{20,000\times 5\times 3}{100}=3,000$, so he repays $23,000$. B covers only one year's interest.
