If, for a particular jacket, N = P + 10, which of the following is closest to the value of N? (One inch is approximately 2.54 centimeters.)

A. 36

Since one inch is approximately 2.54 centimeters, then N centimeters is N/2.54 inches.

Next, since the American size (P inches) is twice the Italian size (N/2.54 inches), then P=2*N/2.54.

As given that N = P + 10, then N=2*N/2.54+10 --> N=~47.

Answer: B.

Bunuel, why do you assume that the answer must be expressed in inches?

P is given in inches. We can add only quantities with the same units, so in this case N and 10 must also represent quantities of inches.
I would say that the question is not well worded...

Quote:
N is the linear distance between the armpits.
2.5P is twice the linear distance between the armpits.


With this, we conclude that 2N = 2.5P or N = 2.5P/2 = 1.25P

Quote:
for a particular jacket, N = P + 10


Now we have two equations, and two variables.

N = P + 10
N = 1.25P

Subtract one from the other, and we get:

N-N = P + 10 - 1.25P
0 = 10 - .25P
.25P = 10
P = 40

Now substitute P = 40 into any of the two equations (such as N = P + 10), and we get N = 50.

Answer choice (B. 47) is the closest value to N = 50.

Hi Bunuel ,
I think i got the same question at MGMAT Prep tests

The Italian size of a suit jacket is N centimeters, where N is the linear distance between the armpits. The American size of a suit jacket is 2.5P centimeters, where 2.5P is twice the linear distance between the armpits. If, for a particular jacket, N = P + 10, which of the following is closest to the value of N?
where in this question it is mentioned that linear length between armpits of American Suit and Italian Suit are same and so we can equate N= 5/4 *P ?
Could you please suggest that Why are we assuming that this is the case ?

Thanks
Lucky

We are asked value of N, which is in cm. So we have to calculate in cm.

Let the distance b/w armpits be "d".
N = P + 10
d = 2d/2.54 + 10
0.212 d = 10
d = 47

B.
