The Italian size of a suit jacket is N centimeters, where N is the linear distance between the armpits when the jacket is laid on a flat surface. The American size of a suit jacket is P inches, where P is twice the linear distance between the armpits when the jacket is laid on a flat surface. 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
B. 47
C. 58
D. 65
E. 72
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.
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 ?
