If 1 * 3 * 5 = 16 ; 3 * 5 * 7 = 38 ; Then find 5 * 7 * 9 =?

Question

If
5 - 4 = 23
8 - 1 = 63
6 -16 = 32
9 - 9 = 78
3 - 9 = 6
then
3 - 81 = ?

Answer 1

1 * 3 * 5 = 16 ( 1+ (3 * 5) = 1 + 15 = 16
3 * 5 * 7 = 38 ( 3 + (5 * 7)= 3 + 35 = 38
So,

5 * 7 * 9 = 5 + (7 * 9) = 5 + 63 = 68.
Answer : 5 * 7 * 9 = 68

Answer 2

1 * 3 * 5 = 16 ( 1+ (3 * 5) = 1 + 15 = 163 * 5 * 7 = 38 ( 3 + (5 * 7)= 3 + 35 = 38So,5 * 7 * 9 = 5 + (7 * 9) = 5 + 63 = 68.Answer : 5 * 7 * 9 = 68
