Exam Problem (as one which came out during May 27 CS Exam)
Mathematics
===========


Problem:
A wood is divided into 4 pcs with a ratio of:
2:3:4:6. If the longest portion is 14 inches,
what is the total length of the wood?
====================================


Solution:


Figure A:
|  2 |   3 |    4    |     6        | = 15
|----|------|--------|------------|
total length of a given:
 = 2 + 3 + 4 + 6 = 15



Let X be the total length


Figure B:
                            |<------ 14 inches ----->|
|-----------------------------------------------------| = x=?



By ratio and Proportion:


Total Length (A)          Total Length (B)
---------------             = -----------------
Longest Length (A)     Longest Length(B)


        15 / 6                 =     X / 14


        (15)(14)
       ---------                =     X
            6
or
                                     (15)(14)      5 (14)      (5) (7)
            X                    = -------     = ------     = ---------
                                             6            2               1


Answer:
          X                       =  35 inches


 / Therefore the Total length is  35 inches. //
