Ten students sit a test consisting of 20 questions. two students get 8 questions correct and one student gets 9 questions correct. the remaining seven students all get at least 10 questions correct and the average number of questions answered correctly by these seven students is an integer. if the average number of questions answered correctly by all ten students is also an integer, then what is that integer?

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.
