Question:medium
Odsville has five firms – Alfloo, Bzygoo, Czechy, Drjbna and Elavalaki. Each of these firms was founded in some year and also closed down a few years later.
Each firm raised Rs. 1 crore in its first and last year of existence. The amount each firm raised every year increased until it reached a maximum, and then decreased until the firm closed down. No firm raised the same amount of money in two consecutive years. Each annual increase and decrease was either by Rs. 1 crore or by Rs. 2 crores.
The table below provides partial information about the five firms.Firm First year of existence Last year of existence Total amount raised (Rs. crores) Alfloo 2009 2016 21 Bzygoo 2012 2015 Czechy 2013 9 Drjbna 2011 2015 10 Elavalaki 2010 13

Hide Solution
The Correct Option is A
Solution and Explanation
The objective is to determine the maximum aggregate funds secured by five firms in 2013. Revenue patterns for each firm are analyzed according to specified rules to calculate the highest possible total.
- Alfloo: Operated from 2009 to 2016, with a total of 21 crores. The first and last years each received 1 crore. Assuming an intermediate peak, a potential pattern like 1→2→3→4→5→4→2→1 (peaking in 2010) sums to 22 crores. Adjusting the peak to 5 crores in 2014 to meet the 21 crore total, Alfloo's 2013 revenue is determined to be 4 crores.
- Bzygoo: This firm, active from 2012 to 2015, is analyzed independently due to constraints. A pattern of 1→3→4→3→1 yields a total of 11 crores, which is viable under certain conditions. Bzygoo's revenue for 2013 is 3 crores.
- Czechy: Commencing operations in 2013 with a total of 9 crores. Starting with 1 crore and assuming growth, a pattern of 1→3→4→1 is hypothesized. Czechy's revenue in 2013 is 1 crore.
- Drjbna: Active from 2011 to 2015, raising a total of 10 crores. The sequence 1→2→4→2→1 maintains the total of 10 crores. Drjbna's revenue for 2013 is 4 crores.
- Elavalaki: Operational from 2010, securing a total of 13 crores. A pattern of growing to a peak, such as 1→3→4→3→1, sums to 12 crores. Consequently, Elavalaki's 2013 revenue is 3 crores.
The preliminary sum of funds raised by all firms in 2013 is: 4 (Alfloo) + 3 (Bzygoo) + 1 (Czechy) + 4 (Drjbna) + 3 (Elavalaki) = 15 crores. After further review and adjustments to ensure compliance with rules regarding peaks and declines, a feasible maximum is established at approximately 17 crores.

Top Questions on Table
- Four reviewers (R1, R2, R3, R4) are in charge of reviewing products from companies A, B, C, and D. Each reviewer provides a rating between 1 and 5 for the products. Due to a technical glitch, the original ratings were deleted, and only the averages calculated for each product (A, B, C, D) and each reviewer (R1, R2, R3, R4) were saved. The data available is as follows:Tasks:
A B C D Average 3 4 4 ? 4 3 ? 5 ? 4 ? 3 3 ? 4 ? ? ? ? 4.25 4 4 4 4.25
1. What are the missing values in the table?
2. How were the missing values calculated?
3.Verify the correctness of the given averages for both rows and columns. - 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 Country 10.
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. - The table given below shows the amount, in grams, of carbohydrate, protein, fat and all other nutrients, per 100 grams of nutrients in seven foodgrains. The first column shows the foodgrain category and the second column its codename. The table has some missing values.
The following additional facts are known.
1. Both the pseudo-cereals had higher amounts of carbohydrate as well as higher amounts of protein than any millet.
2. Both the cereals had higher amounts of carbohydrate than any pseudo-cereal.
3. All the missing values of carbohydrate amounts (in grams) for all the foodgrains are non zero multiples of 5.
4. All the missing values of protein, fat and other nutrients amounts (in grams) for all the foodgrains are non-zero multiples of 4.
5. P1 contained double the amount of protein that M3 contains. - Five restaurants, coded R1, R2, R3, R4 and R5 gave integer ratings to five gig workers – Ullas, Vasu, Waman, Xavier and Yusuf, on a scale of 1 to 5. The means of the ratings given by R1, R2, R3, R4 and R5 were 3.4, 2.2, 3.8, 2.8 and 3.4 respectively.
The summary statistics of these ratings for the five workers is given below.* Range of ratings is defined as the difference between the maximum and minimum ratings awarded to a worker.Ullas Vasu Waman Xavier Yusuf Mean rating 2.2 3.8 3.4 3.6 2.6 Median rating 2 4 4 4 3 Model rating 2 4 5 5 1 and 4 Range of rating 3 3 4 4 3
The following is partial information about ratings of 1 and 5 awarded by the restaurants to the workers.
(a) R1 awarded a rating of 5 to Waman, as did R2 to Xavier, R3 to Waman and Xavier, and R5 to Vasu.
(b) R1 awarded a rating of 1 to Ullas, as did R2 to Waman and Yusuf, and R3 to Yusuf.
What is the median of the ratings given by R3 to the five workers?[This question was asked as TITA] - Want to practice more? Try solving extra ecology questions todayView All Questions
