Directions: The pie charts given below depict the percentage production breakup of 4 crops viz maize, corn, soyabean and wheat in the world and USA respectively. Assume that the total world production of these crops in a given year is160 million tonnes.
In all the questions, 'ROW' means rest of the world other than USA.
Question for LRDI For IIFT 2021
Try yourself:Given that USA accounts for 20 percent of the total production of soyabean in the world then what percentage of the total food crops production of the world is accounted by USA?
Explanation
Given: 20% of total soyabean production of the world is from USA
Thus, Let the total world production of crops be P.
Thus, USA's production of soyabean = 0.2 x 0.35 x P = 0.07P = 7% of the total productions of crops.
Soyabean productions consitutes 25% of the total crop production in the USA.
Thus, percentage of total crop production accounted by the USA = 7% / 2.5 = 28%
Hence, the answer is option C.
Question for LRDI For IIFT 2021
Try yourself:Assume that the total production of maize in the USA is 3 million tonnes. Calculate the percentage (approximately) of the total production of food crops in the world accounted by the USA?
Explanation
The total production of maize in the USA is 3 million tonnes and maize constitutes 40% of the total production of the USA.
Thus, total crop production in the USA = 3/0.4 = 7.5million tonnes.
Thus, the percentage of the total production of crops in the world accounted for by the USA = 7.5 x 100 / 160 = 4.68%
Hence, the answer is option B.
Question for LRDI For IIFT 2021
Try yourself:If the ratio of production of wheat in USA and ROW is 1:6, then(approximately) what percentage of total food crop production of the ROW is accounted by wheat?
Explanation
Total wheat production of the world = 15% of the total crop production of the world
= 15% (Crop production of the USA + Crop production of ROW)
=15%(USA production) + 15%(ROW crop production) ...(1)
To find the percentage of crop production of ROW accounted by wheat, we have to remove the wheat production of the USA.
Wheat production of the USA = 15% (USA production) ...(2)
Thus, the total wheat production of the ROW = 15%(ROW crop production)
Thus, wheat accounts for 15% of the total crop production of the ROW.
Hence, the answer is option D.
Alternately,
Since the wheat accounts for 15% of the total production of the World and the USA, it will also account for the 15% of the total crop production of the ROW.
Question for LRDI For IIFT 2021
Try yourself:USA produces 20 percent lesser corn than ROW, find the production ofsoyabean in USA?
Explanation
Let the total production of crops in the USA, World and ROW be denoted by U, W and R, respectively.
Thus, 0.2(U) = 0.8[0.2W - 0.2U]
0.36U = 0.16W
U = 4/9W
Thus, production of soybean in the USA = 0.25U = 0.25 x 4/9W = 0.25 x 4/9 x 160 = 17.75million tonnes.
Hence, the answer is option D.
Directions: Refer to the following line charts and solve the questions based on them. The line charts given below give the expenditure and income of ABC Ltd. Which produces and sells only two variants of its rice - Basmati rice and Parmal rice.
Question for LRDI For IIFT 2021
Try yourself:The total profit of ABC Ltd. is highest in which of the following years?
Explanation
Option A: Profits for 2007 = 1120 - 360 = 760
Option B: Profits for 2009 = 1420 - 310 = 1110
Option C: Profits for 2012 = 1220 - 560 = 660
Option D: Profits for 2004 = 920 - 460 = 460
Thus, the maximum profit is in the year 2009.
Hence, the answer is option B.
Question for LRDI For IIFT 2021
Try yourself:Calculate the number of years during 2005 to 2013 for atleast one of thetwo rice when income and expenditure did not follow the same trend (i.e both incomeand expenditure did not increase or decrease simultaneously compared to theprevious year)?
Explanation
We have to count the years in which at least one of the rice's income and expenditure shows an opposite trend.
2005: Parmal rice has an opposite trend.
2006: None of the rice has opposite trends.
2007: Basmati rice has an opposite trend.
2008: Basmati rice has an opposite trend.
2009: Both the rice show an opposite trend.
2010: Both the rice show an opposite trend.
2011: Both the rice show an opposite trend.
2012: Basmati rice has an opposite trend.
2013: Basmati rice has an opposite trend.
Thus, all the years except 2008 have at least one rice showing an opposite trend in income and expenditure.
Thus, there are a total of 8 years.
Hence, the answer is option C.
Question for LRDI For IIFT 2021
Try yourself:The percentage annual increase in the income of Basmati rice is highest inwhich of the following years?
Question for LRDI For IIFT 2021
Try yourself:In which year the annual percentage decrease in the profit of parmal rice ismaximum as compared to that of the previous year?
Explanation
Profit for 2008 = 330
Profit for 2009 = 530
Profit for 2010 = 280
Profit for 2011 = 80
Profit for 2012 = 230
Profit for 2013 = 230
From the above trend, we can observe that the maximum decrease is in the year 2011.
Hence, the answer is option C.

Directions: The following graph provides data about the refrigerators and television sets manufactured by XYZ company in 8 days - day1 to day8. However, on each day after quality check (QC) some products were found to be defective. The attached bar chart provides data about aggregate number of refrigerators and televisions manufactured by the company and the number of refrigerators found defective after QC on each day of the given eight days.
All the televisions and refrigerators which cleared the QC were packed for selling.
The bar chart given below provides information about the fraction of the number of televisions found defective to number of televisions which cleared the QC.
Question for LRDI For IIFT 2021
Try yourself:If the number of televisions which cleared the quality check (QC) on each of the given eight days is same, then at least how many refrigerators cleared the QC on day 3?
Explanation
The second chart provides information about the fraction of defective televisions found to the number of televisions that cleared the QC. On day 1, this ratio is 3:4, i.e. let the number of televisions found detective be '3a'. The number of televisions which cleared the QC is 4a, and the total number of televisions is 7a. Similarly, calculating for all the days, we will get the below data.
If T-QC is same for all the days, then they should be in the form of 80k. LCM(4,8,2,5,10,16,5)
T-total on day 3 = 90k
T-total should be maximum to find the minimum value of refrigerators cleared QC.
T-total maximum = 270
Number of refrigerators = 400 - 270 = 130
R-QC = R-total - R-defective = 130 - 100 = 30
Answer is option B.
Question for LRDI For IIFT 2021
Try yourself:On how many of the given 8 days the number of refrigerators which cleared the quality check can be zero?
Explanation
The second chart provides information about the fraction of defective televisions found to the number of televisions that cleared the QC. On day 1, this ratio is 3:4, i.e. let the number of televisions found detective be '3a'. The number of televisions which cleared the QC is 4a, and the total number of televisions is 7a. Similarly, calculating for all the days, we will get the below data.
If the number of refrigerators which cleared the quality check is zero, then the total number of refrigerators is equal to the total number of defective refrigerators.
Televisions = Total manufactured - refrigerators
Day 1: 800 - 100 = 700 is multiple of 7a
Day 2: 600 - 160 = 440 is multiple of 5c
Similarly, calculating for the remaining days, you will get that it is only possible on day 1 and day 2.
The answer is option B.
Question for LRDI For IIFT 2021
Try yourself:Which of the following can be the ratio of number of televisions and refrigerators which cleared the quality check on day1?
Explanation
The second chart provides information about the fraction of defective televisions found to the number of televisions that cleared the QC. On day 1, this ratio is 3:4, i.e. let the number of televisions found detective be '3a'. The number of televisions which cleared the QC is 4a, and the total number of televisions is 7a. Similarly, calculating for all the days, we will get the below data.
The number of televisions which cleared quality check on day 1 = 4a
The number of refrigerators which cleared quality check on day 1 = 800 - 7a - 100 = 700 - 7a
Ratio =
Only option D satisfies the above equation.
The answer is option D.
Question for LRDI For IIFT 2021
Try yourself:Given that the number of televisions which cleared the quality check on each of the eight days is equal to 'X', then how many distinct values of X are possible?
Explanation
The second chart provides information about the fraction of defective televisions found to the number of televisions that cleared the QC. On day 1, this ratio is 3:4, i.e. let the number of televisions found detective be '3a'. The number of televisions which cleared the QC is 4a, and the total number of televisions is 7a. Similarly, calculating for all the days, we will get the below data.
If T-QC is same for all the days, then they should be in the form of 80k. LCM(4,8,2,5,10,16,5)
X = 80k which can take only 3 values, i.e. 80, 160 and 240
Answer is option B.
