Answer:
Consider
Amount of Rice (cups) : Amount of Water(cups)
1.2/5
2. 3/7.5=2/5
3. 5/12.5=2/5
4. 8/20=2/5
As in all cases Amount of Rice and Amount of water in cups are same.
i.e⇒ Amount of rice × K = Amount of water, where K is constant of proportionality.
So, Among all the statements
⇒ The amount of rice is the dependent value. The amount of water is the dependent value are correct.
Which means if either of them (Amount in cups) is given we can find other.
