Answer:
She should pick Corn and Onion as each plant can be grown with 1 litre water. She should not pick Broccoli as this plant needs 2 litres of water to grow.
Step-by-step explanation:
Using the ratios to find out the number of plants that can be grown with 1 litre of water daily.
Corn No. Of Plants Litres Of Water
70 35
x 1
As it is a direct ratio ( i.e the number of plants would increase with every litre increase of water) cross product is used to solve the value of x
x= 70*1/35= 2
2 corn plants can be grown with 1 litre water
Onion No. Of Plants Litres Of Water
440 330
x 1
As it is a direct ratio ( i.e the number of plants would increase with every litre increase of water) cross product is used to solve the value of x
x= 440*1/330= 44/33=4/3= 1.333
1 onion plant can be grown with 1 litre water . 1 litre water will be more for 1 plant.
Broccoli No. Of Plants Litres Of Water
110 220
x 1
As it is a direct ratio ( i.e the number of plants would increase with every litre increase of water) cross product is used to solve the value of x
x= 110*1/220= 0.5
1 broccoli plants can be grown with 2 litre water .
