Solution
Given:• Two reference points, 2015 and 2017, to compare the values of sales of gluten-free labelled products
To find:• The percentage increase of the sales values of gluten-free labelled products, from 2015 to 2017
Approach and Working: Analysing Statement 1• As per the information given in Statement 1, products labelled gluten-free accounted for 2.4% of the value of all the product sold in 2015. This does not provide any information about:
o The total sales value of all the products in 2015 and,
o The sales value of gluten-free products in 2017
• Therefore, it is not possible to find the percentage increase from Statement 1 alone
Analysing Statement 2• As per the information given in Statement 2, products labelled gluten-free accounted for 7.2% of the value of all the product sold in 2017. This does not provide any information about:
o The total sales value of all the products in 2017 and,
o The sales value of gluten-free products in 2015
• Therefore, it is not possible to find the percentage increase from Statement 2 alone
Combine both statementsCombining the information given in the statements, we can say that:
• Gluten-free products accounts for 2.4% and 7.2% of the total sales value in 2015 and 2017 respectively
o But this information does not provide any additional data regarding their specific sales value in those 2 years mentioned
o Also, this information does not provide any additional data regarding the values and change of the total sales in those 2 years
• Without either of the information mentioned above, it is not possible to find out the exact percentage change
Hence the correct answer is Option E
Answer: E
