Read the following passage and answer the question :

Indira Gandhi canal, previously known as the Rajasthan canal, is one of the largest canal systems in India conceived by Kanwar Sain in 1948, the canal project was launched on 31 March 1958. The canal originates at Harike barrage in Punjab and runs parallel to Pakistan border at an average distance of 40 Km in Thar Desert (Marusthali) of Rajasthan. The total planned length of the system is 9,060 Km, catering to the irrigation needs of a total culturable command area of 19.63 lakh hectares. Out of the total command area, about 70 percent was envisaged to be irrigated by flow system and rest by lift system. The construction work of the canal system has been carried out through two stages. The command area of Stage-I lies in Ganganagar, Hanumangarh and northern part of Bikaner districts. It has a gently undulating topography and its culturable command area is 5.53 lakh hectares. The command area of stage-II is spread over Bikaner, Jaisalmer, Barmer, jodhpur, Nagaur and Churu districts covering culturable command area of 14.10 lakh ha. It comprises desert land dotted with shifting sand dunes and temperature soaring to 50° C in summers. In the lift canal, the water is lifted up to make it flow against the slope of the land. All the lift canals of Indira Gandhi canal system originate at the left bank of main canal while all the canals on the right bank of main canal are flow channels.

Which of the following represents the percentage of command area irrigated by lift system?

30 percent

The correct answer is Option (2) → 30 percent

In the context of the canal system mentioned, the information provided indicates that the irrigation needs of the total command area were planned to be met through a combination of two systems: the flow system and the lift system.

Distribution between Flow and Lift Systems: The information specifies that about 70 percent of the total command area was envisaged to be irrigated by the flow system. Therefore, the remaining percentage, which is not covered by the flow system, represents the portion irrigated by the lift system. Since 70 percent is allocated to the flow system, the lift system would cover the remaining 30 percent.
