Question

If the weight of an elephant is \[4000kg\] and a blue whale weighs \[30\] times that of an elephant, then what is the weight of a blue whale?
\[(A)125500kg\]
\[(B)125000kg\]
\[(C)120000kg\]
\[(D)114862kg\]

Answer 1

Hint: In the question the weight of the elephant is given and the weight of the blue whale is thirty times the weight of an elephant. So, we will apply the weight of the elephant directly in the given condition. The higher vertebrates who are warm-blooded are called mammals like an elephant and blue whale, etc.

Formula used:
Blue whale weight= \[30 \times \]weight of an elephant.

Complete step-by-step solution:
Given, the weight of elephant =\[4000kg\]
Blue whale weight= \[30 \times \]weight of an elephant.
Blue whale weight= \[30 \times 4000kg\]
Blue whale weight=\[120000kg\].
Hence, the weight of a blue whale is\[120000kg\].

Additional information:
The mammals carry with them mammary glands that have the property to supply milk, give birth to young ones, and also they need hairs in their body. The example of mammals is human beings, dogs, cats, cows, monkeys, etc.
The largest existing land mammal on Earth is the elephants. The legs of the elephant carry his weight which appears like a pillar. They need an extended nose, or trunk, floppy ears, and thick legs. The neatest creature is the Elephant who has the largest brain out of all animals. The weight of the animal is approximate\[2 - 7tons\].
The largest and heaviest mammal is the blue whale of the world that lives on Earth. The length of the blue whale is \[100feet\] and weight is\[200tons\]. The only tongue of the blue whale weighs as much as an elephant. The body of the blue whale is high-span and slender. It is a marine mammal. The lifespan of a blue whale is approximately\[73years\]. These mammals are at the point of extinction.

Note: So we noted that the largest mammal within the world is the blue whale. It’s a marine or aquatic mammal. It comes out of the water to complete the respiration process in his body. The blue whale is dying day by day that’s why their population is coming to an endpoint of extinction. There are fewer than \[5\] species of blue whales left. We must always protect them and don’t let them become extinct.
