Which of the following inferences can be drawn from the above graph?
Let's analyze the given graph to determine which inferences can be drawn:
Inference 1: The total number of students qualifying in Physics in 2015 and 2014 is the same.
The graph shows that in 2014, there is a 10% increase in Physics and the same in 2015. This suggests individual increases rather than equality; thus, this inference is incorrect.
Inference 2: The number of students qualifying in Biology in 2015 is less than that in 2013.
In 2015, there is a 10% decrease in Biology. Hence, the number of students qualifying in Biology in 2015 is indeed less than that in 2013, making this inference correct.
Inference 3: The number of Chemistry students qualifying in 2015 must be more than the number of students who qualified in Biology in 2014.
The graph shows an 8% increase in Chemistry for 2015 and a 5% increase in Biology for 2014. Without actual numbers, it's impossible to compare, so this inference is not supported.
Inference 4: The number of students qualifying in Physics in 2015 is equal to the number of students in Biology that qualified in 2014.
Since both show a 10% change, this can suggest equality only when the base numbers are equal, which we don't know.
Conclusion: The correct inference is that the number of students qualifying in Biology in 2015 is less than that in 2013.
