In order to win the contest, they should use less water. Let us analyze their usage.

Tom takes a bath in a swimming pool that too daily whereas jerry takes a bath only on Sundays. Swimming pools consume a lot of water as compared to bathing in the bathroom. So, Jerry conserves more water.

Drip irrigation is a technique to minimize water consumption for irrigation by using underground pipe system which delivers water directly to the base of the plant, whereas sprinklers use jets of water to irrigate which leads to wastage of water. Thus, Jerry conserves more water here too.

Again, collecting rainwater is a good practice to save water, This is called rainwater harvesting. So, Jerry wins this task.
Construction work consumes a lot of water and moreover increased population increases the use of water. So, in this activity also Jerry wins

Hence, we see that Jerry saves a lot of water in his activities and he wins the competition.
