Let the number of bottles be x and the time in hours be y.
Number of bottles Time in hours
x₁ = 840 y₁ = 6
x₂ = ? y₂ = 5
So, the number of bottles filled, and numbers of hours are directly proportional to each other.
Two numbers x and y are said in direct proportion if, the relationship between two quantities is such that if we increase one, the other will also increase, and if we decrease one the other quantity will also decrease.

Answer:
(d)
Step-by-step explanation:
If machine fill 840 bottles in 6 hours
6hours =840
1hours = ?
= 840÷6 = 140 in 1 hours
if 1 hours = 140 then 4 hours what
1= 140
4 = ?
140×4 = 560
answer. 700
Step-by-step explanation:
Let the number of bottles be x and the time in hours be y.
Number of bottles Time in hours
x₁ = 840 y₁ = 6
x₂ = ? y₂ = 5
So, the number of bottles filled, and numbers of hours are directly proportional to each other.
Two numbers x and y are said in direct proportion if, the relationship between two quantities is such that if we increase one, the other will also increase, and if we decrease one the other quantity will also decrease.
x/y = k, x = ky
where k is a constant.
Thus, x₁ / y₁ = x₂ / y₂
840 / 6 = x₂ / 5
6x₂ = 840 × 5
x₂ = (840 × 5) / 6
x₂ =700
Thus, 700 bottles can be filled in 5 hours
