Q.1 If 21y5 is a multiple of 9, where y is a digit, what is the value of y?
Ans
If a number is a multiple of 9, then the sum of its digits will be divisible by 9.
Sum of digits of 21y5 = 2 + 1 + y + 5 = 8 + y
Hence, 8 + y should be a multiple of 9.
This is possible when 8 + y is any one of these numbers 0, 9, 18, 27, and so on …
Since y is a single digit number, therefore, y can be 1 only.
Q.2 If 31z5 is a multiple of 9, where z is a digit, what is the value of z? You will find that there are two answers for the last problem. Why is this so?
Ans
If a number is a multiple of 9, then the sum of its digits will be divisible by 9.
Sum of digits of 31z5 = 3 + 1 + z + 5 = 9 + z
Hence, 9 + z should be a multiple of 9.
This is possible when 9 + z is any one of these numbers 0, 9, 18, 27, etc.
Since z is a single digit number, the sum can be either 9 or 18.
Therefore, z should be either 0 or 9.
Q.3 If 24x is a multiple of 3, where x is a digit, what is the value of x?
Ans
If a number is a multiple of 3, then the sum of its digits should also be a multiple of 3.
Since 24x is a multiple of 3, the sum of its digits is a multiple of 3.
Sum of digits of 24x = 2 + 4 + x = 6 + x
Hence, 6 + x is a multiple of 3.
This is possible when 6 + x is any one of these numbers 0, 3, 6, 9, and so on.
Since x is a single digit number, the sum of the digits can be 6 or 9 or 12 or 15.
Thus, the value of x comes to 0 or 3 or 6 or 9 respectively.
Therefore, x can have any of the four different values 0, 3, 6, or 9.
Q.4 If 31z5 is a multiple of 3, where z is a digit, what might be the values of z?
Ans
If a number is a multiple of 3, then the sum of its digits should also be a multiple of 3.
Since 31z5 is a multiple of 3, the sum of its digits will be a multiple of 3.
That is, 3 + 1 + z + 5 = 9 + z is a multiple of 3.
This is possible when 9 + z is any one of 0, 3, 6, 9, 12, 15, 18, and so on.
Since z is a single digit number, 9 + z= 9 or 9 + z= 12 or 9 + z= 15 or 9 + z= 18
Therefore, the value of z = 0 or z = 3 or z = 6 or z = 9.
