Read the given passage and answer the questions that follow.
On May 2, 2018, severe dust storms and thunderstorms hit parts of Rajasthan, Uttar Pradesh, and other adjoining regions. Explaining the reasons behind such severe weather systems, M. Mohapatra, a senior scientist with the India Meteorological Department (IMD), said that dust storms and thunderstorms are a result of nearly similar weather conditions, like intense heat. Areas that have moisture in the air experience thunderstorms, while those that don't have moisture experience dust storms. "All such conditions were being fulfilled on that day. The region had moist easterly winds coming from the Bay of Bengal, and there was a western disturbance system too. All this together triggered the events on May 2," he added.
In simple terms, a dust storm can be explained as a phenomenon that occurs when strong winds carry dust over an extensive area.
As far as the timing of their occurrence is concerned, Mohapatra stated that there is no deviation in the time of occurrence of a dust storm or thunderstorm activity, as they usually peak in the pre-monsoon period.
These events happen between March and May only. In the pre-monsoon period, temperatures are very high, around 44–45 degrees Celsius, and lead to such activities.
Even though dust storms and thunderstorms are a common feature every year, there has been no focused work on studying the trends related to them. "In the coming years, there could be more instances of intense thunderstorms and sand storms, but they have to be studied in detail, looking at the data from over 30 to 40 years to notice a trend. Work has been more or less confined to cyclones and monsoon systems, but not much on dust storms or thunderstorms. It needs study," admitted Mohapatra.
The extent of damage caused by thunderstorm activity in India can be gauged from the data of India's National Crime Records Bureau (NCRB). As per the NCRB data, compared to other natural disasters like cyclones, floods, or heat waves, lightning kills more people in India. For instance, at least 25 percent of the 10,510 accidental deaths attributable to forces of nature in 2015 were due to lightning. The number of deaths due to lightning has constantly remained over 2,000 every year since 2005.
Question:
A dust storm mainly occurs due to:
Option 1: moisture in the air
Option 2: easterly wind
Option 3: intense heat
Option 4: extreme cold
Correct Answer: intense heat
Solution : The third option is the correct choice (refer to the first paragraph).
As explained by M. Mohapatra in the passage, both dust storms and thunderstorms are a result of nearly similar weather conditions, particularly intense heat. He mentions that areas experiencing intense heat without

Option 4: IJK
Correct Answer: LNM
Solution : Let's check each option –
First option: XYZ→X + 1 = Y; Y + 1 = Z Second option: LNM→L + 2 = N; N – 1 = M Third option: ABC→A + 1 = B; B + 1 = C Fourth option: IJK→I +
Question : Distance covered by object is ________to time.
Option 1: equal proportional
Option 2: directly proportional
Option 3: inversely proportional
Option 4: double proportional
Correct Answer: directly proportional
Solution : The correct option is directly proportional.
Distance is the measure of how far an object has travelled, typically measured in units such as metres or kilometres.
Distance is a scalar quantity, meaning it has only magnitude and no direction.
Question : A train covers the distance between station A and station B in 45 minutes. If the speed of the train is reduced by 5 km/hr, then the same distance is covered in 48 minutes. The distance between stations A and B is:
Option 1: 60 km
Option 2: 64 km
Option 3: 80 km
Option 4: 55 km
Correct Answer: 60 km
Solution : Let the distance between the two stations be $x$ km. So, the speed of the train is $\frac{x}{\frac{45}{60}}=\frac{4x}{3}$ km/hr According to the question, $\frac{x}{\frac{4x}{3}-5}=\frac{48}{60}$ ⇒ $\frac{x}{\frac{4x-15}{3}}=\frac{48}{60}$ ⇒ $\frac{3x}{4x-15}=\frac{4}{5}$ ⇒ $16x-60=15x$ ⇒ $x=60$ km Hence, the correct answer is 60 km.
Question : Directions: If a mirror is placed on Line MN, which of the options will be the right image of the given figure?

Question : The following table shows the data of different colleges whose students participated in the Olympiad.
What is the percentage increase in the number of students who participated in the GK Olympiad to those who participated in the Science Olympiad from all colleges? (Correct to two decimals places.)
Option 1: 29.37%
Option 2: 29.89%
Option 3: 29.74%
Option 4: 29.01%
Correct Answer: 29.37%
Solution : Students participated in GK Olympiad = 182 + 200 + 120 + 130 + 183 = 815 Students participated in Science Olympiad = 100 + 100 + 150 + 200 + 80 = 630 Difference = 815 – 630 = 185 $\therefore$ Required percentage =
