Question

If
2+4+6=19,
3+6+9=43,
4+6+8=53
then
9+5+3=?

Answer 1

9*5+9*3-(9-1) = 64

Answer 2

2+4+6=19 => (2x4)+(2x6)-1=19
3+6+9=43 => (3x6)+(3x9)-2=43
4+6+8= 53 => (4x6)+(4x8)-3=53
9+5+3=? => (9x5)+(9x3)-4=68
ANS: 68

Answer 3

It follows the logic below:
(4 + 6) x 2 - 2 + 1 = 19
(6 + 9) x 3 - 3 + 1 = 43
(6 + 8) x 4 - 4 + 1 = 53
Then,
(5 + 3) x 9 - 9 + 1 = 64

The answer is 64
