Question

a bike requires 5liters of petrol to cover 80km.How many litres of petrol are required to cover 32km​

Answer 1

GIVEN :-

• 80 KM required 5 liter petrol

TO FIND :-

• petrol required to cover 32 km

SOLUTION :-

now we know that

$\implies \rm{5 \: ltr = 80 \: km}$

$\implies \rm{1\: ltr = \dfrac{80}{5} \: km}$

$\implies \rm{1\: ltr = 16\: km}$

$\implies \rm{(1 \times 2)\: ltr = (16 \times 2)\: km}$

$\implies \rm{2\: ltr = 32\: km}$

$\implies \boxed{ \boxed{ \rm{so, \: 2 \: ltrs \: petrol \: required \:to \: cover \: 32 \: km }}}$
