Question

a tin of two stroke petrol mixture holds 3.9 L. if the mixture is made from petrol and oil in the ratio 25:1 find the amount of oil in the mixture

Answer 1

Answer:

When engine oil accidentally mixes with petrol fuel, it can lead to engine damage due to poor lubrication from the contaminated oil. ... This would make the car 'run rich' with more fuel than air, a situation which leads to delivering excessive amounts of fuel in the combustion chamber.

Answer 2

Step-by-step explanation:

Holding capacity of tin =3.9 L

Let the composition of petrol and oil be '25x' and 'x'

Therefore,

whole compostion =25x+x=26x

now

26x=3.9L

x=3.9/26

x=39/260

x=3/20L

x=0.15L

Therefore, composition of oil is 0.15L

(You can also take out composition of petrol by multiplying result of 'x' by 25 ,i.e. the ratio of petrol , which will give you >>3.75 L.)

(Hope it helps .)
