doomedcat · Answer

1) Suff, as the ratio is > 1 , then it indicates that numerator is greater than denominator , hence bill for feb > bill for jan,

2) Insuff, As total is given and we cannot bifurcate the individual values of bills

Ans A)

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

Avinash2303 · Answer

1. Feb/Jan = 26/25. Clearly, Feb>Jan i.e. Sufficient

2. Jan + Feb = ....We cannot fetch the value of each variable. Not Sufficient.

Chandru1996 · Answer

I don`t think there is good explanation for this question for those who are new to quant 
Assume variable for easiness
Let feb bil be f and january bil be j

Q) was f>j ?

(1) The ratio of the amount of John's heating bill for February to that for January was 26/25.
we can interpret this as 26x/25x
x is the common multiplier use logic to answer now 
x is gonna be same for both the values so if 25*anything will always be lesser than 26*anything
clearly sufficient

(2) The sum of the amounts of John's heating bills for January and February was $183.60.
Total doesnt help us we need splits "
insufficient

Solution:

Question Stem Analysis:

We need to determine whether the amount of John's heating bill in February was greater than it was in January.

Statement One Alone :

Since the ratio of the amount of John’s heating bill in February to that in January was greater than 1, the amount of John’s heating bill in February was indeed greater than it was in January. Statement one alone is sufficient.

Statement Two Alone:

Knowing the total amount paid for the two months does not allow us to determine whether the amount for February was greater than that for January. Statement two alone is not sufficient.

Answer: A

Since the ratio of the amount of John’s heating bill in February to that in January was greater than 1, HOW?

NamDuong · Answer

For Yes/No question in Data sufficiency, a statement(s) allows you to give a single, definitive answer to the question asked.
If a statement(s) always provides YES for every possible values, it is sufficient 
If a statement(s) always provides NO for every possible values, it is sufficient 
If a statement(s) provides YES/NO depending on specific values, YES for some values while NO for some others, it is insufficient 
 If a statement(s) allows for    both    a "Yes" and a "No," it is    Insufficient

So for statement 1, for infinite pairs of positive values as bills of February 'x' and January 'y' that satisfy x/y=26/25, x is always greater than y (x > y) 
Therefore statement 1 alone is sufficient
