Question Discussion & Solution

According to given conditions,

Clearly, the man is now facing West.

Hence, ‘West’ is the correct answer.

Concept:

• Water Harvesting: Water harvesting is a practice to conserve water by collecting rainwater in an organized way.
  • The rainwater is not allowed to flow and get wasted but collected in tanks.
  • The main purpose however is not the collection but the enhancement of groundwater level.  
  • The collected water through tubes is made to recharge groundwater.
  • Maintenance of groundwater is long term sustainable structure for water conservation.

Here the logic is the methods which consumes water:

Explanation:

Kneading:

• Kneading is a process in the making of dough by mixing water and flour.
• Example: Kneading dough for roti. 
• Consumes water

Swimming also need water to do so.

Washing clothes is also a process that consumes.

While combing hair, no need of water.

The correct answer is Rajasthan.

Key Points

• 'Ghaggar and Banas' are rivers that feed the state of Rajasthan.
• The Ghaggar is an intermittent river in India, flowing during the monsoon rains.
  • It originates in the village of Dagshai in the Shivalik Hills of Himachal Pradesh at an elevation of 1,927 meters (6,322 ft) above mean sea level and flows through Punjab and Haryana states into Rajasthan.
  • The main tributaries of the Ghaggar are the Kaushalya river, Markanda, Sarsuti, Tangri and Chautang.
• Banas River :
  • The Banas is a river that lies entirely within the state of Rajasthan in western India.
  • It is a tributary of the Chambal River, itself a tributary of the Yamuna, which in turn merges into the Ganga.
  • It flows northeast through the Mewar region of Rajasthan, then across Hadavati before meeting the Chambal near the village of Rameshwar in Sawai Madhopur District.

The logic is:

In the first letter E is added six then we get K similarly in the second letter F is added six the

we get L.

Similarly, in the first letter T is added six then we get Z and in the second letter U is added six then we get A.

49 ÷ 7 = 7,

70 ÷ 7 = 10,

91 ÷ 7 = 13,

99 ÷ 7 = 14.14

So, 49, 70 and 91 are the multiples of 7 while 99 is not a multiple of 7.
