The square of each diff.

What level?

I beg to disagree on that 4 as the answer.

The answer is 24.

9+5 =16 This means you can replace 16 with 9 + 5, since they are equal in this context.

13+7 = 36 also same here. 18 is half of 36. If 36 is (13 +7) in the context, then 18 is half of 13+7. That's (13+7)/2

(By method of substitution)
18 + 16 = ((13+7)/2) + (9 + 5) = 10 + 14 = 24

The question says If 9+ 5 = 16, not if 9 - 5 = 16. The if was an assumption, so we work with the assumption. No where it was assumed that 9 - 5 = 16 on the question.

Deepthoughts:
Your answer may be correct but did the initial question followed mathematical logic?,,I do not think it's logical to expect one to begin to change the mathematical signs from the original form to solve questions as there are mathematical rules as to when signs can be changed,like crossing the equal sign but in this case there was nothing like that.

Its not Mathematics.
its Quantitative / Logical Reasoning.

you Remember Quantitative Aptitude don't you?

I beg u in the name of God

The answer is 4.

18-16= 2.

2 square is 4

4 is the answer

What is the answer to this logical question

subtract n square....it has nothing to do with addition. The "+" is there to derail your thought.


18 + 16 = (18-16)² = 4
The answer is 4

This is the right thing to do.
You already have more than enough

reality abeg i fit see 1k for your hand.i got banned at politics section before e.ejo giveaway and i couldnt comment even though i saw the giveaway earlier

Anything no small abeg just do me small thing

The answer is 4

I charge high for using my brain...note!

The answer is 4. Simple!
All you have to do is square the answer after subtracting 16 from 18

1. For 9 + 5:
9x5-19-5)=45-4=16

2. For 6 + 3:
6x3-（6-3） = 18-3=9

3. For 13 + 7:
13 × 7- (13-7) = 91-6=36

The pattern holds, so we'll apply it to 18 + 16.
Calculation for 18 + 16:
18x16-（18-16） =288-2=286

Answer:
18 + 16 = 286

This is twisted and corrupt logic.

All wrong answers so far

It's (15 ×15)!


Edit: Now I see the solution; I was wrong. Nevertheless, We keep trying.

What is the answer to this logical question

The answer is 4.

1. For 9 + 5:
9-5=4, 4*4=16

2. For 6 + 3:
6-3=3, 3*3=9

3. For 13 + 7:
13-7=6, 6*6=36

Exactly my point.

It's a mathematical riddle. Riddles is a mystifying, misleading, or puzzling question posed as a problem to be solved or guessed

So it may not be 💯 mathematical... it's just to test the IQ

I beg to disagree with you.
Any mathematical riddle that failed to obey mathematical fundamental principle is not a riddle.
