## Number Puzzle # 63

Check your answer:- See Explanation

Answer is 28

How?

Right side number is equal to the sum of the digits on left side multiplied by 2

for ex.

11 + 11 => (1+1+1+1)*2

Thus

16 + 16 => (1+6+1+6)*2 = 28.

2+4=6

6*2=12

13+13 =26

2+6=8

8*2=16

14+14=28

2+8=10

10*2=20

Andy says

Alternatively it can be 10

16+16=32

3+2=5

5*2 = 10

28

Quasselkasper says

i have guessed 28 – but only because it increments with 4 each time. Is there a “deeper” rule?

Sanjay Saket says

its sum of each digit X 2

Mike Walker says

Example of what Sanjay is saying

11+11=8 —– (1+1+1+1)2=8

12+12=12 —- (1+2+1+2)2=12

13+13=16 —- (1+3+1+3)2=16

14+14=20 —– (1+4+1+4)2=20

so

16+16=28 —- (1+6+1+6)2=28

Personally, I found the answer the same way Quasselkasper found it. and I believe that it makes more sense.

For each incremental number, add 4 to the previous answer.

With Sanjay’s explanations

both 5+5 and 14+14 equal 20 which isn’t mathematically sound.

The way Quasselkasper and I found it 5+5=-20
