Dans un magasin, un vélo coûte 34,000 gourdes et il est soldé au prix de 25,000 gourdes. Quel est le pourcentage de la réduction par rapport au prix initial ?

a) [tex]7.35 \%[/tex]

b) [tex]36 \%[/tex]

c) [tex]26.47 \%[/tex]

d) [tex]2.64 \%[/tex]



Answer :

To determine the percentage reduction of the price of a bicycle that was originally priced at 34000 gourdes and is now sold for 25000 gourdes, we need to follow these steps:

1. Find the amount of reduction: Subtract the sale price from the initial price to find out how much the price has been reduced.

[tex]\[ \text{Reduction Amount} = \text{Initial Price} - \text{Sale Price} \][/tex]

[tex]\[ \text{Reduction Amount} = 34000 \, \text{gourdes} - 25000 \, \text{gourdes} = 9000 \, \text{gourdes} \][/tex]

2. Calculate the percentage reduction: To find the percentage reduction, we use the reduction amount and divide it by the initial price, then multiply by 100 to convert it to a percentage.

[tex]\[ \text{Percentage Reduction} = \left( \frac{\text{Reduction Amount}}{\text{Initial Price}} \right) \times 100 \][/tex]

[tex]\[ \text{Percentage Reduction} = \left( \frac{9000 \, \text{gourdes}}{34000 \, \text{gourdes}} \right) \times 100 \approx 26.47\% \][/tex]

So, the percentage reduction relative to the initial price is approximately [tex]\(26.47\%\)[/tex].

Therefore, the correct answer is:
c) [tex]\(26,47\%\)[/tex]
