Josea was not prepared for her recent geometry quiz, so for each multiple-choice problem, she randomly guessed man answer out of four possibilities. What do you expect her score to be, as a percentage out of 100%?

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.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
