Yes, the answer is 259. But think: any real number is divisible by 3. Did you intend to put another requirement in the question?
Not exactly 86 x 9 = 774 87 x 9 = 783 so not an exact number 777/9 = 86.3333 86 times with 3 remaining 777 - 3 = 774 = 9 x 86
1, 3, 7, 13, 21, 37, 39, 91, 111, 259, 273, 481, 777, 1443, 3367, 10101
39% of 777 = 39% * 777 = 0.39 * 777 = 303.03
12% of 777 = 12% * 777 = 0.12 * 777 = 93.24
