  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,

  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
