What digits should come in place of X and Y if the number 62684xy is divisible by both 8 and 5?
The whole number turns out to be either 6268400 or 6268440 or 6268480. # should equals to 0,since it should be an even number (divisible by 8) and should be divisible by 5. The condition that a number to divisible by 8 is that the last three digits should divisible by 8. Therefore ,4@0 is divisible by 8 when @=0 or 8.
What is the general form of two digit number if it is divisible by 3?
For a number in the generalized form: A general two-digit number 10x + y is divisible by 3 if (x + y) is divisible by 3. A general three-digit number 100a + 10b + c is divisible by 3 if (x + y + z) is divisible by 3.
Which digits should come in place of * and?
Hence, digits in place of * and $ are 4 and 0 respectively.
Which digit should come in a place of a star and dollar if the number 4675 star to dollar is divisible by both 5 and 8?
Aptitude | Arithmetic Aptitude 6 | Question 1 Which digits should come in place of * and $ if the number 4675*2$ is divisible by both 5 & 8? Explanation: Since the given number is divisible by 5, 0 or 5 must come in place of $.
How can you write a two digit number AB in general form?
Numbers can be written in general form. Thus, a two digit number ab will be written as ab = 10a + b. The sum of a 2-digit number and the number obtained by interchanging its digits is always divisible by 11.
Which numbers do not pass the divisibility test?
Examples of numbers that are do not pass this divisibility test. Since the last two digits, 13, are not divisible by 4, the whole number does not pass this divisibility test. The last two digits, 41, are not de visible by 4. Therefore, the whole number does not satisfy the rule for 4. Those last two digits, 14, do not work.
What are the rules for divisibility by 6?
Since 6 is a multiple of 2 and 3, the rules for divisibility by 6 are a combination of the rule for 2 and the rule for 3. In other words, a number passes this divisibility test only if it passes the test for 2 and the for 3. Rule: A number is divisible by 6 if it is even and if the sum of its digits is divisible by 3.
What are the numbers that are divisible by 4?
Examples of numbers that are divisible by 4: Since the last two digits, 12, are divisible by 4, the number 112 is also divisible by 4. The last two digits, 48, are divisible by 4. Therefore, the whole number is also. Yep, this satisfies rule because 88 is divisible by 4!
Is the whole number 1011 divisible by 4?
Since the last two digits, 13, are not divisible by 4, the whole number does not pass this divisibility test. 10,941: The last two digits, 41, are not de visible by 4. Therefore, the whole number does not satisfy the rule for 4. 100,002,014: Those last two digits, 14, do not work.-1,011: 11 is not divisible by 4, so 1,011 fails this test.
