$Logic math puzzle with two answers$

1+4=5

2+5=12

3+6=21

8+11=?

The two answers to the puzzle are 40 and 96.

If the answer is 40

Solution

1+4=5

2+5=7+5=12

3+6=9+12=21

11+8=19+21=40

If the answer is 96

1+4=5 (obvious).

Then multiply the two numbers and add the first number to the product.

2+5 = (2×5)+2=10+2= 12.

The next is 3+6= 21= (3×6)+3 =18+3= 21.

Finally.

8+11= (8×11)+8= 88+8= 96.
