Solution

To find:
• Whether the value of 4x is less than y

Analysing Statement 1
• As per the information given in Statement 1, 4x + y > 7
o From this, 4x can be greater or less than y.
• For example, if y = 20 and 4x = 24, then 4x > y. Alternatively, if y = 16 and 4x = 12, 4x < y. In both the cases 4x + y > 7.
• Hence, statement 1 is not sufficient to answer

Analysing Statement 2
• As per the information given in Statement 2, y > 15
o But this statement does not provide any information about x (or 4x)
• Hence, statement 2 is sufficient to answer the question

Combining Both Statements
• If we combine both the statements, we can say 4x + y > 7 and y > 15
o We can take the same set of values that we took in statement 1 and say both possibilities exist( 4x > y or 4x < y).
• Thererfore, we cannot answer even after combining the statements.

Hence, the correct answer is option E.
