What is the mode of 31, 29, 33, 37, 43, 38, 33 and 40

33

Step-by-step explanation:

The answer is 33 since it is the number that is most repeated.

That is was the mode is.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
