Answer:

2 cups of water

Step-by-step explanation:

Given ratio for a batch of rice:

water : rice = 20 : 10 (cups)

Let x = cups of water needed for 1 cup of rice:

⇒ 20 : 10 = x : 1

write as fractions:

⇒ 20 / 10 = x / 1

cross multiply:

⇒ 20 × 1 = x × 10

⇒ 20 = 10x

solve for x:

⇒ x = 20/10

⇒ x = 2

Therefore, 2 cups of water are needed for 1 cup of rice.
