Data Interpretation: SSC CGL Practice Questions

Q. 1 Direction: In the following table, the production of various crops (in tonnes) is given from 2015 to 2019. Study the table and answer the question that follows. Year | Rice | Wheat | Sugarcane | Barley | Maize ——- | ——– | ——– | ——– | ——– | ——– 2015 | 415 | 2500 | 1000 | 975 | 490 2016 | 520 | 4218 | 1120 | 825 | 550 2017 | 585 | 3482 | 1250 | 700 | 610 2018 | 625 | 4500 | 1325 | 725 | 780 2019 | 600 | 3300 | 1450 | 775 | 840 What is the percentage decrease in the production of wheat in 2019 compared to 2018? (correct to two decimal places)

Check Solution

Ans: B

Explanation: To calculate the percentage decrease, we use the formula: ((Original Value – New Value) / Original Value) * 100.
In this case, the original value is the wheat production in 2018 (4500 tonnes) and the new value is the wheat production in 2019 (3300 tonnes).
Percentage decrease = ((4500 – 3300) / 4500) * 100 = (1200 / 4500) * 100 = 0.26666… * 100 = 26.67%.

Q. 2 Direction: The table given below shows the ratio of cars and Bikes manufactured by 5 different companies. The table also shows the ratio of three different types of cars C1, C2 and C3 and three different types of bikes B1, B2 and B3 manufactured by these 5 different companies. Total numbers of car and bikes together manufactured by D, E, F, G and H are 300000, 280000, 320000, 400000 and 480000 respectively.

Let X = Total number of C3 type cars manufactured by all companies. Let Y = Total number of B1 type bikes manufactured by company E, F and H together. What is the value of X / Y?

Check Solution

Ans: C

Explanation: The question cannot be answered without the table containing the ratios of cars and bikes manufactured by each company, the distribution of car types (C1, C2, C3) and bike types (B1, B2, B3) for each company, and the total number of cars and bikes manufactured by each company. The question provided is incomplete.

Q. 3 The following table shows the age-wise ownership of television sets. | Brand | Less than 1 year old | 1-3 years old | 3-5 years old | More than 5 years old | |—|—|—|—|—| | X | 20% | 30% | 30% | 20% | | Y | 15% | 25% | 40% | 20% | | Z | 10% | 20% | 25% | 45% | If 10,000 television sets of Brand Y are sold till date, how many are either 1-3 years old or more than 5 years old?

Check Solution

Ans: D

Explanation:
1. **Identify the relevant percentages for Brand Y:** The question asks for the number of Brand Y televisions that are either 1-3 years old or more than 5 years old. From the table, we see these percentages are 25% and 20% respectively.
2. **Calculate the combined percentage:** Add the percentages for the two age groups: 25% + 20% = 45%.
3. **Calculate the number of TVs:** Multiply the total number of Brand Y TVs (10,000) by the combined percentage (45% or 0.45): 10,000 * 0.45 = 4500

Q. 4 The following table shows the sales (in Rs. crore) of a company from 2018 to 2022. Year | Sales (Rs. Crore) 2018 | 150 2019 | 175 2020 | 200 2021 | 225 2022 | 250 What is the total sales of the company (in Rs. crore) during this period?

Check Solution

Ans: B

Explanation: To find the total sales, we need to add the sales figures for each year. 150 + 175 + 200 + 225 + 250 = 1000

Q. 5 The table below shows the monthly expenses (in rupees) of four families, P, Q, R, and S, categorized by their source. | Family | Rent | Food | Transportation | Utilities | Entertainment | Total | |—|—|—|—|—|—|—| | P | 15,000 | 20,000 | 4,000 | 3,000 | 2,000 | 44,000 | | Q | 12,000 | 18,000 | 3,500 | 2,500 | 1,500 | 37,500 | | R | 10,000 | 25,000 | 5,000 | 4,000 | 3,000 | 47,000 | | S | 8,000 | 15,000 | 2,000 | 1,000 | 500 | 26,500 | How many families spend more than half of their total expenses on food?

Check Solution

Ans: A

Explanation: To determine how many families spend more than half their total expenses on food, we need to calculate the percentage of expenses spent on food for each family and compare it to 50%.

Family P: (20,000 / 44,000) * 100 = 45.45%
Family Q: (18,000 / 37,500) * 100 = 48%
Family R: (25,000 / 47,000) * 100 = 53.19%
Family S: (15,000 / 26,500) * 100 = 56.60%

Families R and S spend more than 50% on food. So there are 2 such families.

Q. 6 The table below shows the number of times different colors are used in a painting: Color | Frequency ——- | ——– Red | 45 Blue | 110 Green | 60 Yellow | 90 Purple | 45 Which colors appear less than 70 times?

Check Solution

Ans: A

Explanation: The question asks for the colors that appear less than 70 times. Looking at the table: Red appears 45 times, Blue appears 110 times, Green appears 60 times, Yellow appears 90 times, and Purple appears 45 times. The colors that appear less than 70 times are Red, Green, and Purple. Therefore, the correct option is D.

Q. 7 The table shows the production of rice (in tonnes) by five different farmers over four years. Farmers Year P Q R S T 2018 120 150 130 180 140 2019 150 170 160 190 160 2020 140 160 170 200 150 2021 180 190 180 210 170 What is the total production of rice by farmer R over the given years?

Check Solution

Ans: C

Explanation: To find the total production of rice by farmer R, we need to sum the production of rice by farmer R for each of the given years. From the table, farmer R’s production is: 2018: 130 tonnes, 2019: 160 tonnes, 2020: 170 tonnes, 2021: 180 tonnes. Adding these values: 130 + 160 + 170 + 180 = 640 tonnes.
