Question : The price of an article is first increased by 25% and later on, the price was decreased by 30% due to a reduction in sales. Find the net percentage change in the final price of the article.
Option 1: 11.5% increased
Option 2: 14% decreased
Option 3: 13% increased
Option 4: 12.5% decreased
Correct Answer: 12.5% decreased
Solution : Let the original price of the article be 100. After a 25% increase, the new price $=100 + 25 = 125$ Then, a 30% decrease on the new price $=125 - \frac{30}{100}\times 125 = 87.5$ The net percentage change $=\frac{{\text{Final price} - \text{Initial price}}}{\text{Initial
Question : Comprehension: Read the following passage and answer the questions that follow. Unlike its Nordic neighbours, Sweden decided early on in the pandemic to forgo lockdown in the hope of achieving broad immunity to the coronavirus. While social distancing was promoted, the government allowed bars, restaurants, salons, gyms, and schools to stay open. Initially, Sweden saw death rates from COVID-19 that were similar to those of other European nations that had closed down their economies. But now, the Scandinavian nation's daily death toll per 1 million people is 8.71 compared to the United States 4.59, according to the online publication 'Our World in Data'. Sweden's mortality rate is the highest in Europe. "I'd say it hasn't worked out so well," said Dr. George Rutherford, professor of epidemiology at the University of California, San Francisco. "I think the mortality in Norway is something like ten-fold lower. That's the real comparator." (Norway's daily death rate is less than 0.01 per 1 million people.) "If you let this go, don't try very hard, or go about it in somewhat of a more restrained way than we have here, this is the price you pay," Rutherford said. "Maybe it didn't hurt businesses, but you have twice the mortality rate of the United States. All those people who died were part of families, and they were citizens and part of the fabric of Swedish society. And now they're gone because of a policy that hasn't worked out quite the way they thought it would." Scientists estimate herd immunity for the coronavirus is reached when 70–90% of the population becomes immune to a virus, either by becoming infected or getting a protective vaccine. Despite its relaxed response, Sweden is nowhere near hitting that goal. Tests on 1,118 Stockholm residents carried out by Sweden's Public Health Agency over one week in late April showed that only 7.3% had developed the antibodies needed to stave off the disease. "I think herd immunity is a long way off if we ever reach it," Björn Olsen, a professor of infectious medicine at Uppsala University, told Reuters after the release of the antibody findings. Rutherford said we can keep doing non-pharmaceutical interventions like contact tracing, mask-wearing, and isolation quarantines, but also develop drugs that work better treating people who already have the infection so they don't require critical care in a hospital.
Question: What was the result of having no lockdown in Sweden?
Option 1: Sweden's mortality rate became the highest in Europe.
Option 2: The economy in Sweden flourished more than before.
Option 3: Sweden has achieved herd immunity against the Corona virus.
Option 4: Sweden's public health care system became more robust.
Correct Answer: Sweden's mortality rate became the highest in Europe.
Solution : The correct choice is the first option
Explanation: The passage illustrates that despite forgoing a lockdown and pursuing a strategy aiming at achieving broad immunity to the coronavirus, Sweden's mortality rate due to COVID-19 was now the highest
Question : The area of a square is 100 sq. cm. Find the length (in cm) of its diagonal.
Option 1: $10\sqrt{2}$
Option 2: $10$
Option 3: $20\sqrt{2}$
Option 4: $20$
Correct Answer: $10\sqrt{2}$
Solution : The area of a square is given by the formula $A = s^2$, where $s$ is the length of a side. Given that the area is 100 sq. cm. $s = \sqrt{A} = \sqrt{100} = 10 \text{ cm}$ The length of the diagonal $d$ of
Question : If $x$ is subtracted from each of the numbers 20, 37, 54 and 105, then the numbers so obtained in this order are in proportion. What is the mean proportional between $(7 x-5)$ and $(x+1) $?
Option 1: 8
Option 2: 9
Option 3: 6
Option 4: 12
Correct Answer: 8
Solution : If $x$ is subtracted from each of the numbers 20, 37, 54 and 105, then the numbers so obtained in this order are in proportion. So, $\frac{(20-x)}{(37-x)} = \frac{(54-x)}{(105-x)}$ $⇒[(20-x)(105-x)]=[(54-x)(37-x)]$ $⇒34x=102$ $⇒x = 3$ The mean proportional between $(7x-5)$ and $(x+1)$ is the square root
Question : Directions: Select the option figure in which the given figure (X) is embedded as its part. (Rotation is not allowed.)
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : As there is a restriction on the rotation of the figure, we will check where the question figure can exactly fit itself in the given option figures. By comparison of all the option figures, the given question figure is embedded only in the fourth option figure.
Question : In a circle, the length of a chord is 30 cm. The perpendicular distance of the chord from the centre of the circle is 8 cm. Find the diameter of the circle.
Option 1: 28 cm
Option 2: 34 cm
Option 3: 17 cm
Option 4: 30 cm
Correct Answer: 34 cm
Solution : Let AB be the chord and O be the center of the circle. Also, OP is perpendicular to AB In $\triangle$ OPB, OB2 = PB2 + OP2 ⇒ OB2 = 152 + 82 ⇒ OB2 = 225
