Answer:

∴ [tex]2[/tex] litres of petrol is required to cover [tex]80[/tex] km.

Step-by-step explanation:

• In context with question asked,
• We have to find the amount of litres of petrol is required to cover [tex]80[/tex] km.
• It is given that,

  The distance covered by two wheeler in [tex]5[/tex] litres of petrol = [tex]200[/tex] km

• Let, [tex]x[/tex] be the amount of litres of petrol is required to cover [tex]80[/tex] km.
• So, the required ratio becomes,

          [tex]\frac{x}{80} =\frac{5}{200}[/tex]

• By cross multiplication, we get

        ∴ [tex]200x=80\times 5[/tex]

         ∴ [tex]200x=400[/tex]

             ∴ [tex]x=\frac{400}{200}[/tex]

             ∴ [tex]x=2[/tex]

• ∴ [tex]2[/tex] litres of petrol is required to cover [tex]80[/tex] km.
