Pick one.
A) 20	B) 24	C) 16	D) 28	E) 30
== 3:4:5   Total parts = 12   = The largest number value is 40   = The largest number is = 5   = Then 5 parts -----&gt; 40 ( 5 * 8 = 40 )   = smallest number = 3 &amp; Largest number = 5   = Difference between smallest number &amp; largest number is = 5 - 3=

<output>2</output>
2= Then 2 parts -----&gt; 16 (2 * 8 = 16)   16
<result>C</result>
