  1. On dividing a certain number by 357, the remainder is 39. On dividing the same number by 17, what will be the remainder ?
    1. 5
    2. 3
    3. 7
    4. 6
  1. Correct Option: A

    Let the given number be N
    Therefore N = 357k + 39
    Then,
    357 k + 39 = ( 17 x 21k ) + ( 17 x 2 ) + 5
    ∴ Required remainder = 5
