Answer:
(D) 2.8L
Step-by-step explanation:
The ratio to prepare lemonade is 7:200
let the lemon and water mixture be 7x and 200x respectively
if 1 lemon contain = 14 ml juice
then 7 lemon will contain = 14*7 ml juice
= 98ml
lemon is 7x= 98ml
x = 98/7
= 14 ml
as we know x= 14 ml
then 200x = 200*14 ml
= 2800ml
1000ml= 1 liter
2800ml= 2.8 liter (answer)
