lateral thinking - Grandpa has another non math question

Grandpa says, " This is not algebra or may be it is!

IF

X = 2

R + C = 6

B + P = 5 or 6

Then

What is

I + T ?

There are, with my logic, three different answers!"

Answer

Here’s a thought...

X = 2

X is said like the word “ex” = 2 letters

R + C = 6

“are” plus “cee” (or “see” or “sea”) = 6

B + P = 5 or 6

“be” or “bee” plus “pee” (or “pea”) = 5 or 6

Thus, I + T =

Any of “I”, “ai”, “ay”, “aye” or “eye”, plus “tee” (or “tea”) = 4,5, or 6

for three solutions using the same logic, as requested.

... and “ti” would actually allow four answers, 3 4 5 or 6 :)
