hello said...

cool brain teasers they are a lot of fun :3

Could you help me to solve this one:
1= 2
26 = 3
79 = 4
3 = 5

Could you help me to solve this one:
1= 2
26 = 3
79 = 4
3 = 5
? = 6

Rajesh Kumar said...

Can you please re-check the first term 1=2 or 1=3?

Abdul said...

Tell us what number 3 is

Unknown said...

I don't think that's it since 3=5 already, I did it my way where they substitute each other, but I can't find a reason why 79=4 so I can't prove myself right, right now I substituted everything and have this
1=2
1+4=5
?=6
3=5
4=6
that /=6 is what I can't proof, I'm not saying I'm right by any means, but I wish help to see if you can find a connection through my perspective of substitution and adding the connected numbers

Unknown said...

nvm I just realized I have small brain and I used all the numbers previously to add up to 6 so my whole theory is incorrect

Unknown said...

A=1, B=2, C=3 and so one till Z=26
So G+A = 7 + 1 = 8.
