When a number is divided by 6,the remainder is 2 , i.e. If the number is added 4, it is a multiple of 6When it is divided by 9,the remainder is 5, i.e. when the number is added 4, it is a multiple of 9
When divied by 15, the remainder is 11 , i.e. when the number is added 4 , it is a pultiple of 15
LCM of 6 , 9 , 15 = 90
Therefore, the number = 90 - 4 = 86
