Nancy has 43 peaches and 15 pears left at her roadside fruit stand. She went to the orchard and picked more peaches to stock up the stand. There are now 53 peaches at the stand. How many did Nancy pick?

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.
