Hi,
According to me the logic and answer should be
5 4 = 45-36 =9
Add firs two digits(5 4) : 5+4 = 9
Multiply the result (5+4 = 9) with the first digit (5) : 9 X 5 = 45
Multiply the result (5+4 = 9) with the second digit (4) : 9 X 4 = 36.
Therefore the answer should be
9 4 = ? = ?
Add two numbers 9+4 = 13
Multiply the result (9+4 = 13) with the first digit (9) : 13 X 9 = 117
Multiply the result (9+4 = 13) with the second digit (4) : 13 X 4 = 52.
9 4 = 117-52 = 65
*Note 6 7 = 78-51 =27 is inconsistent with said solution and should be 6 7 = 78-91 = -13
I think where you have written 51, there should be 91.
