The question does not provide any information about how much money the kid has. So obviously you need both statements to answer the question. Ans is C.

(C) 2008 GMAT Club - m04#22

Statement (1) ALONE is sufficient, but Statement (2) ALONE is not sufficient
Statement (2) ALONE is sufficient, but Statement (1) ALONE is not sufficient
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient
EACH statement ALONE is sufficient
Statements (1) and (2) TOGETHER are NOT sufficient

[Reveal] Spoiler:
OA C...IMO B


Let T : the total value of Johnny's coin T=85
X : the number of quarter in Johnny's pocket
Y: the number of nickel in Johnny's pocket ;

Hence, (0.25*X) + (0.05*Y) = 85
Since X>Y (Johnny has more quarters than nickels in his pocket)

X and Y can have different values .
For example : x = 339 , y= 5

Or x= 338, y = 10

Or x = 337, y = 15

Thus, the answer should be E.

Plz Correct if i'm wrong ..

Hi,


And has to be C

Let there by x no. Of quarter and y nickels.We need to find x

Now st 1 says

x*0.25+y*.05= 85 cents

There are many possible values such as below
x=3 and y=2 or x= 2, y = 7 or x=1 and y=12

There fire not suff

St 2 says x>y

Alone not sufficient

Combining we see that only possible value will be x= 3 and y= 2


Thanks
Mridul

Since 1 quarter = $0.25 = 25 cents and 1 nickel = $0.05 = 5cents ; the correct equation is : 25x + 5y = 85
Now it becomes clear.

thanks Mridul

C

With B only you could have 8 Q's and 7 N's, or 9 Q's and 7 N's...we don't have a total value so impossible to determine.

Generally if problem is dealing with positive numbers i.e amounts, dollars if one denomination is a multiple of another denominations, multiple solutions are possible.

here 0.05 is a multiple of .25 hence first statement alone is not sufficient to solve the problem
statement 2 states the one denomination is greater than the other, hence both together are required Option C
