Question : The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
She seemed / to be / in hurry / to leave.
Option 1: in hurry
Option 2: to be
Option 3: She seemed
Option 4: to leave

Question : If 7 people working 4 hours a day can complete a task in 14 days. The number of days taken by 12 people working 8 hours a day will be:
Option 1: $5 \frac{1}{8}$ days
Option 2: $8$ days
Option 3: $4 \frac{1}{12}$ days
Option 4: $7 \frac{1}{4}$ days
Correct Answer: $4 \frac{1}{12}$ days
Solution : Total work = Number of people × Number of hours per day × Number of days $= 7 \times 4 \times 14 = 392$ Let $x$ be the number of days required. So, $392 = 12\times 8\times x$ $\therefore x = \frac{392}{96} =
Question : If $x=\frac{\sqrt{5}-\sqrt{4}}{\sqrt{5}+\sqrt{4}}$ and $y=\frac{\sqrt{5}+\sqrt{4}}{\sqrt{5}-\sqrt{4}}$ then the value of $\frac{x^2-x y+y^2}{x^2+x y+y^2}=$?
Option 1: $\frac{361}{363}$
Option 2: $\frac{341}{343}$
Option 3: $\frac{384}{387}$
Option 4: $\frac{321}{323}$
Correct Answer: $\frac{321}{323}$
Solution : $x=\frac{\sqrt{5}-\sqrt{4}}{\sqrt{5}+\sqrt{4}} = \frac{(\sqrt{5}-\sqrt{4})^2}{(\sqrt{5}+\sqrt{4})(\sqrt{5}-\sqrt{4})} = \frac{5+4-4\sqrt5}{5-4} = 9-4\sqrt5$ $y=\frac{\sqrt{5}+\sqrt{4}}{\sqrt{5}-\sqrt{4}} = \frac{(\sqrt{5}+\sqrt{4})^2}{(\sqrt{5}-\sqrt{4})(\sqrt{5}+\sqrt{4})} = \frac{5+4+4\sqrt5}{5-4} = 9+4\sqrt5$ ⇒ $xy=\frac{\sqrt{5}-\sqrt{4}}{\sqrt{5}+\sqrt{4}}×\frac{\sqrt{5}+\sqrt{4}}{\sqrt{5}-\sqrt{4}}=1$ and $x+y=9-4\sqrt5+9+4\sqrt5=18$ Now, $\frac{x^2-x y+y^2}{x^2+x y+y^2}$ = $\frac{x^2+2xy+y^2-3xy}{x^2+2xy+y^2-xy}$ = $\frac{(x+y)^2-3xy}{(x+y)^2-xy}$ = $\frac{(18)^2-3}{(18)^2-1}$ = $\frac{321}{323}$ Hence, the correct answer is $\frac{321}{323}$.

Question : Comprehension: Read the following passage and answer the questions given after it.
At the end of 2020, there were 82.4 million forcibly displaced people in the world, of which more than a quarter are refugees.
"By the end of 2020, the number of people forcibly displaced due to persecution, conflict, violence, human rights violations, and events seriously disturbing public order, had grown to 82.4 million, the highest number on record according to available data," according to the UN High Commissioner for Refugees (UNHCR). Out of these 82.4 million forcibly displaced people in the world, more than a quarter are refugees.
Just five countries produce 68% of all refugees displaced abroad: the Syrian Arab Republic, Venezuela, Afghanistan, South Sudan, and Myanmar.
The top five host countries, where these displaced people are currently located are Turkey, Colombia, Germany, Pakistan, and Uganda.
With 3.7 million displaced people now within its borders, Turkey hosts twice as many refugees as Colombia, the next highest host country, with 1.7 million people. The situation in Turkey illustrates the effects of proximity, as 92% of its refugees have come from neighbouring Syria, where war and armed conflict have now been raging for more than 10 years. It demonstrates that huge numbers of displaced people stay close to their point of origin.
There are more than 48 million internally displaced people - people who have had to flee their homes in search of safety elsewhere within their home nation.
The highest increases in the number of internally displaced people happened in Africa and were provoked by a combination of armed conflict and humanitarian disasters. The civil war in Ethiopia, Africa's second most-populated country, has sparked a wave of displacement in a region that was already facing what the UNHCR calls "a full-scale humanitarian crisis."
All in all, more than a million Ethiopian people had to leave their homes behind last year, the UNHCR says.
