Question

I am a number bigger than 156 and some other than 166 when I am divided by 9 one leave a reminder 7 what number am I

Answer 1

160, idea is go through the 9s table number should be greater than 156 but less than 166. So check the number between 156-166 having 9s table you will get number as 162 and you want to get remainder 7 as well so 162+7 = 169 which won't satisfy our condition so take 153 (17*9) and add 7 which gave 160
