Question

If 1=3

2=3

3=5

4=4

5=4

Then, 6=?

Answer 1

9514 1404 393

Answer:

3

Explanation:

For "a = b" it appears that the intention is b = f(a). It appears that f(a) is the number of letters in the spelling of 'a'.

"One" has 3 letters

"Two" has 3 letters

"Three" has 5 letters

"Four" has 4 letters

"Five" has 4 letters

"Six" has 3 letters

so, 6 = 3.

Additional comment

This appears to be a non-standard use of the equal sign, in which it has no relation to the usual meaning of "equals." Using standard symbols with non-standard meanings should generally be avoided, unless the intended meaning is explained.
