Question 1158669
.
<pre>

By standing on formal positions of the English language, I can (and I should) interpret the condition 
as if Amy is 5 times as old as James


Let x = the James' age; then the Amy's age is 5x, according to my interpretation.


Then I can write this equation


    (5x - 3) + (x-3) = 54

    6x = 54 + 6 = 60

    x           = 60/6 = 10.


So, my answer is:  Amy is 5*10 = 50 years.

It is very difficult question: how to interpret.


Formally, English requires exactly this interpretation.


But, practically, in the everyday life, another interpretation just prevales.




The TRUTH is: in your mathematical composing and writing NEVER USE this form  

<pre>
    "X is 4 times older than Y", 
</pre>since it ALWAYS leads to confusing and misinterpretation.



Use this equivalent phrasing

<pre>
    "X is 5 times as old as Y".
</pre>instead. Then everybody will understand you by an UNIQUE WAY, and you will avoid misunderstanding.
