Solution
To find:
- • Whether the amount of John’s heating bill for February greater than that of January
Analysing Statement 1
- • As per the information given in statement 1, the ratio of the amount of John's heating bill for February to that for January was \(\frac{26}{25}\).
- o From this we can say, \(\frac{February-Bill}{January-Bill} = \frac{26}{25} = 1 + \frac{1}{25}\) which is always >1
o Therefore, February bill > January bill
Hence, statement 1 is sufficient to answer
Analysing Statement 2
- • As per the information given in statement 2, the sum of the amounts of John's heating bills for January and February was $183.60
- o From this, we cannot find out the bills for January and February separately
Hence, statement 2 is not sufficient to answer
Hence, the correct answer is option A.
Answer: A
