What best can be concluded about the number of times the AC must have either been turned on or the AC
temperature setting been altered between 11:01 pm and 1:59 am?
Video Explanation

What was the temperature outside, in degree Celsius, at 9 pm?
Video Explanation

Video Explanation

How many times the AC must have been turned off between 11:01 pm and 1:59 am?
Video Explanation

The air-conditioner (AC) in a large room can be operated either in REGULAR mode or in POWER mode to reduce
the temperature.
If the AC operates in REGULAR mode, then it brings down the temperature inside the room(called inside
temperature) at a constant rate to the set temperature in 1 hour. If it operates in POWER mode, then this is
achieved in 30 minutes.
If the AC is switched off, then the inside temperature rises at a constant rate so as to reach the temperature
outside at the time of switching off in 1 hour.
The temperature outside has been falling at a constant rate from 7 pm onward until 3 am on a particular night.
The following graph shows the inside temperature between 11 pm (23:00)and 2 am (2:00) that night.
The following facts are known about the AC operation that night.
• The AC was turned on for the first time that night at 11 pm (23:00).
• The AC setting was changed (including turning it on/off, and/or setting different temperatures) only at the
beginning of the hour or at 30 minutes after the hour.
• The AC was used in POWER mode for longer duration than in REGULAR mode during this 3-hour period.

Video Explanation

Out of 10 countries -- Country 1 through Country 10 -- Country 9 has the highest gross domestic product (GDP),
and Country 10 has the highest GDP per capita. GDP per capita is the GDP of a country divided by its
population. The table below provides the following data about Country 1 through Country 8 for the year 2024.
• Column 1 gives the country's identity.
• Column 2 gives the country’s GDP as a fraction of the GDP of Country 9.
• Column 3 gives the country’s GDP per capita as a fraction of the GDP per capita of Country10.
• Column 4 gives the country’s annual GDP growth rate.
• Column 5 gives the country’s annual population growth rate.
Assume that the GDP growth rates and population growth rates of the countries will remain constant for the
next three years

Assume that the annual rate of growth in PAT over the previous year (ARG) remained constant over the
years for each of the six firms. Which among the firms A, B, C, and E had the highest ARG?
Video Explanation

The two plots below give the following information about six firms A, B, C, D, E, and F for 2019 and 2023.
PAT: The firm's profits after taxes in Rs. crores,
ES: The firm's employee strength, that is the number of employees in the firm, and
PRD: The percentage of the firm's PAT that they spend on Research and Development (R&D).

The PRD values of each firm are proportional to the areas around the points representing each firm. The areas are comparable between the two plots, i.e., equal areas in the two plots represent the same PRD values for the two years.
