Total weight of 43 children = 1448 + 42.3 + 39.7 + 39.5 = 1569.5 kg
So, the required average weight = $\frac{1569.5}{43}$ = 36.5 kg
Hence, the correct answer is

Question : If $\left(w+\frac{1}{w}\right)=6$, then what will be the value of $\left(w-\frac{1}{w}\right)?$

Option 1: $4 \sqrt{2}$

Option 2: $\sqrt{2}$

Option 3: $3 \sqrt{2}$

Option 4: $2 \sqrt{2}$

Team Careers360 24th Jan, 2024

Correct Answer: $4 \sqrt{2}$


Solution : Given: $\left(w+\frac{1}{w}\right)=6$
Squaring both sides, we have,
⇒ $\left(w+\frac{1}{w}\right)^{2}=6^{2}$
⇒ $w^{2}+\frac{1}{w^{2}}+2=36$
⇒ $w^{2}+\frac{1}{w^{2}}=34$
⇒ $w^{2}+\frac{1}{w^{2}}-2=34-2$
⇒ $(w-\frac{1}{w})^{2}=32$
⇒ $(w-\frac{1}{w})=\sqrt{32}$
$\therefore(w-\frac{1}{w})=4\sqrt{2}$
Hence, the correct answer is $4\sqrt{2}$.

Question : Comprehension:
Read the passage and answer the questions.

It is a truth universally acknowledged that every happy home should have a dog. Ours was a happy family, but we missed a dog. Our family comprised of four siblings: the parents and the grandfather. Our grandfather, whom we called Dadaji, was an awesome person—a strict disciplinarian and a bit whimsical.
One fine morning, happiness exploded in our courtyard. Our maid had rescued a puppy from being crushed on the road, and she came straight to our house. He was the cutest puppy we had ever seen. He was not a pedigreed one, but he was intelligent and had playful eyes. His white coat bore dark black tiger stripes. No sooner had he come to our house than he started playing with us as if he had found his old friends. Our maid called him Moti, and it was approved by all instantly.
But there was a catch. Dadaji never liked dogs. Our happiness was doused with the clearly visualised apprehension that Dadaji would throw away the puppy along with the maid from the house. Sensing the problem, our mother devised a cogent argument to convince him of the utility of the puppy. Mother tried to convince Dadaji that the puppy, when he grew up, would protect the house against thieves. Dadaji looked at the puppy in a measured way and derisively commented, “Let’s see,” and reclined on the easy chair with a newspaper in his hands. It was typical of him—every time he would concede somebody's argument, he would recline on his favourite easy chair with a newspaper.
For three months, ours was the happiest family in the world.
But dogs will be dogs. Moti committed a huge mistake. Our dadaji used wooden sandals with leather straps as footwear.
On that fateful night, Moti, with nothing else attracting his attention, smelled something leathery and started chewing the leather straps off the sandals. By morning, the leather straps were reduced to smithereens.
When Dadaji woke up in the morning and lowered his feet to wear the sandals, he was aghast.
The sandals were missing.
In the courtyard, he saw the shocking scene of the total destruction of his sandals. From disbelief to anger, and from anger to rage, within two minutes, Dadaji was a fireball. “Where is Moti?” he shouted, heaving heavily. All of us, including Mom, were looking for cover. Moti, too, realised his mistake and its consequences. He sheepishly sneaked behind the dining table. But his fate had been sealed.

Option 1: The night when thieves entered the house.
