10 divisibility questions for SSC and other number system questions in SSC CGL Set 46 - time to answer 12 mins

Problem 1.

Two numbers 7655 and 11284 when divided by a third number of three digits, the remainder left in both cases is same. The sum of the digits of the three digit number is then,

1. 9
2. 11
3. 10
4. 8

Problem 2.

The value of $(0.34\overline{68}+0.17\overline{32})$ is,

1. $0.52\overline{01}$
2. $0.\overline{51}$
3. $0.52$
4. $0.5\overline{1}$

Problem 3.

If $p$ and $q$ are positive integers and $(p-q)$ is an even number, then $(p^2-q^2)$ will always be divisible by,

1. 4
2. 6
3. 12
4. 8

Problem 4.

3957 is added to 5349 and 7062 is subtracted from the resulting sum. The final result is then not divisible by,

1. 3
2. 4
3. 7
4. 11

Problem 5.

If the sum of digits of any integer lying between 100 and 1000 is subtracted from the number, the result will always be divisible by,

1. 9
2. 6
3. 2
4. 5

Problem 6.

1. 8
2. 7
3. 9
4. 10

Problem 7.

When a number is divided by 56, the remainder left is 29. What will be the remainder when the number is divided by 7?

2. 3
3. 1
4. 2

Problem 8.

64329 is divided by a certain number getting 175, 114 and 213 as three successive remainders. The divisor is then,

1. 296
2. 234
3. 184
4. 224

Problem 9.

A number when successively divided by 4 and 5 leaves remainders 1 and 4 respectively. The remainders left when the number is divided by 5 and 4 successively will be,

1. 1, 4
2. 2, 1
3. 2, 3
4. 3, 2

Problem 10.

If two numbers are each divided by the same number the remainders are respectively 4 and 3. If again the sum of the numbers are divided by the same divisor, the remainder now is 2. The divisor is,

1. 3
2. 9
3. 5
4. 7
