total 17x=15.5
x=0.911 ~1
1\$ = 10 dimes
5*10= 50 dimes option C

Friend according to me answer should be B
As nickels is equal to 5cents
dimes is equal to 10 cents
and quartlet is equal to 25 cents

let us assume there are 2x,5x and 10x coins of nickels, dimes and quartets respectively
so total value is 10x, 50x and 250x = 310X cents
then x=1550/310= 5
No of dimes will be equal to 25

AKY13 I agree. Nickel is not a standard unit. It is used colloquially. I do not think GMAC expects the world to know what "nickel" and "dime" are !
I had to Google to know what worth is a dime mikemcgarry will GMAC expect us to know the value of nickel and dime? I know even if it doesn't we should have that kinda knowledge. I just wish to know that does GMAC take into account the global knowledge or is it concerned only about US standards?

Don't stress about it, Aditya. Terms "Nickel, dimes & quarter" are not used in US but are in Canada.
I have no doubts that it must be provided. These kind of things are not part of worldly knowledge we are expected to have. Without this conversion provided, the question is not complete.
One must have the knowledge of basic conversions such as Dollar to cents.

Hi AKY13,

I would like to make one small correction. Nickels, dimes, pennies, and quarters are very much commonly used currency coins here in the US. The only less commonly used currency coins are half a dollar coin and a dollar coin.

B. 25
C. 50
D. 85
E. 155

The ratio of coins is N : D : Q = 2x : 5x : 10x.

We can create the equation for the money value of the coins, in cents, as:

5(2x) + 10(5x) + 25(10x) = 1550

10x + 50x + 250x = 1550

310x = 1550

x = 5

So there are 5(5) = 25 dimes in the jar.

Hi csaluja
Even if it is used in US but not popular outside US, the conversion must be provided. Quant is test not of worldly knowledge but of quantitative aptitude. GMAT gives conversion of units of length within SI units as well viz. cm to mm or vice versa. Although we must know them as we(in India) ALL studied these units conversion before we passed Xth standard.
