A number, y, is equal to twice the sum of a smaller number and3. The larger number is also equal to 5 more than 3 times the smaller number.

step-by-step explanation:

no of data

divide by no of mode

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.
