If the three digit number 24x is divisible by ‘9’, what is the value of ‘x’?
For a number to be divisible by 9, the sum of its digits must be divisible by 9.
Here, 2 + 4 = 6. Next multiple of 9 is 9.
Therefore, we will add 9  6 = 3. So, the value of x = 3.
By which of the following number 9042 is not divisible? 2, 3, 6, and 9
Identify the missing digit in the number 234,4_6, if the number is divisible by 4.
By which of these numbers is the number 3116365 divisible?
The last digit is 5, the number is divisible by 5.
Since
311636 − 10 = 311626 ÷ 7 = 44568,
the number is divisible by 7 also.
A number divisible by 3 and 4 is divisible by 12.
If the division N ÷ 5 leaves a remainder of 0, what might be the one’s digit of N?
ANSWER : b
Solution : If a number is divisible by 5 then it's unit digit must be 0 or 5. so if we need the remainder of 0 when divided by 5 then the numbers unit digit must be 0 or 5.
10 ×5 = 50
6 = 6
⇒ 50 + 6 = 56
B+1=8
B=7, A+7=1 .So A=4 and B=7
Divisible by 2 and 3 both.
If the division N ÷ 2 leaves no remainder (i.e., zero remainder), what might be the one’s digit of N?
Since every multiple of 2 leaves no remainder when divided by 2.Therefore N can be ,0,2,4,6 or 8
We can write acb=100*a+10*c+b which say that a is at hundred’s place, c is at ten’s place and b is at one’s place.
If the division N ÷ 5 leaves a remainder of 4, what might be the one’s digit of N?
Since every multiple of 5 ends with either 5 or 0. Therefore, the unit digit of N must be either 0+4=4 or 5+4=9. Hence the answer is either 4 or 9.
