Answer:
366329, Multiply the first digit and the second and then the first and last.Those 2 products will be the first four digits.Add those two values and then subtract them with the last digit.That will be the last 2 digits.
Step-by-step explanation:
3 x 5 = 15, 3 x 6 = 18, 15 + 18 = 33, 33 - 6 = 27, On reversing = 72
5 x 5 = 25, 5 x 6 = 30, 25 + 30 = 55, 55 - 6 = 49, On reversing = 94
5 x 6 = 30, 5 x 7 = 35, 30 + 35 = 65, 65 - 7 = 58, On reversing = 85
5 x 5 = 25, 5 x 3 = 15, 25 + 15 = 40, 40 - 3 = 37, On reversing = 73
Therefore, 9 x 4 = 36, 9 x 7 = 63, 36 + 63 = 99, 99 - 7 = 92, On reversing = 29
9 + 4 + 7 = 366329
