Question : Comprehension:
Read the passage and answer the questions.
The Ganges River Dolphin or Gangetic Dolphin, is the national aquatic animal of India. The elusive freshwater cetacean is an umbrella species of the Ganga and Brahmaputra river system and has significant ecological importance as its presence indicates the good health of an area. The species is listed under the 'Endangered' category of the International Union for the Conservation of Nature as it is losing its habitat. These animals were once found in large groups called 'schools' but nowadays, the groups have reduced in size. The Vikramshila Gangetic Dolphin Sanctuary in Bihar's Bhagalpur district, the only sanctuary for our national aquatic animal, is facing a decline in its dolphin population. On the other hand, there are some deep pools in the Ganga river system outside of Vikramshila, where the dolphins are prospering. I came across one such deep-water pool recently. It is situated in the Ganga near Dhakwa village of Varanasi district, Uttar Pradesh. The village is a 45-minute ride away from Sarnath. Since there is no tourism in the area, Brijesh (one of our local co-workers, who is involved in the Namami Gange project) requested one of the fishermen to take us to the middle of the river and he agreed. This man had a traditional wooden boat that could accommodate four people. I saw five to six dolphins in those waters. It seemed like dolphins were used to having boats around them. I visited the place quite a few times as I found that it was the best to see Gangetic dolphins jumping near one's boat without them getting bothered about human presence. It definitely is a sign of a healthy section of the highly polluted Ganga. I am glad that people out there are conserving the area by not altering its serenity. I wish we could find more such places and try and conserve the dolphins before they vanish from our river systems. It can be an interesting place to have on your bucket list if you are a nature lover. I assume that there are at least 10 dolphins living happily in that spot. Locals say they have seen these majestic mammals for the past many years and do not catch them. In rare cases, if a dolphin gets caught in their nets, they let it go without harming it. I never imagined such a habitat near the crowded and polluted patch of the Ganga that is Varanasi.

Question:
The presence of dolphins in the Ganga and Brahmaputra river systems indicates:

Option 1: the decline in the dolphin population

Option 2: the high level of pollution in the area

Option 3: the sound health of the habitat

Option 4: the threat to the species

Team Careers360 18th Jan, 2024

Correct Answer: the sound health of the habitat


Solution : The third option is the correct answer.

The passage mentions that the Gangetic Dolphin has significant ecological importance, and its presence indicates the good health of an area. So, the presence of dolphins in the Ganga and Brahmaputra river systems

Question : 51% of a whole number is 714. What is 25% of that number?

Option 2: 450

Option 3: 550

Option 4: 250

Team Careers360 17th Jan, 2024

Correct Answer: 350


Solution : Let the number be $x$.
