Ok, let's try to find the value of the dividend based on the given information
=> 30 is the divisor
=> The dividend is a 3 digit number, which is the least
=> Remainder of 8
To get the answer, let's find the least number that can be divided with 30
=> 30 * 1 = 30
=> 30 * 2 = 60
=> 30 * 3 = 90
=> 30 * 4 = 120, the least 3 digit number that is divisible with 30
Now, let's add 8 as a reminder
=> 120 + 8 = 128
=> 128//30 = 4 reminder 8
Hope this helps you =)
