On dividing a number by 5, we get 3 as remainder. What will be the remainder when the square of this number is divided by 5 ?
  • 0
  • 1
  • 2
  • 4
+ View Answer
  • Answer
  • d) 4
  • Solution
  • Let the number be x and on dividing x by 5, we get k as quotient and 3 as remainder.
    x = 5k + 3 => x²
    = (5k + 3)²
    = (25k² + 30k + 9)
    = 5(5k² + 6 k + 1) + 4
    On dividing x² by 5, we get 4 as remainder.

The difference of two number is 1365. On dividing the large number by the smaller, we get 6 as quotient and 15 as remainder. What is the smaller number ?
  • 240
  • 270
  • 295
  • 360
+ View Answer
  • Answer
  • b) 270
  • Solution
  • Let the smaller number be x. Then larger number = (x + 1365)
    x + 1365 = 6x + 15 => 5x = 1350 => x = 270.
    Smaller number = 270.

On dividing 2272 as well as 875 by 3-digit number N, we get the same remainder. The sum of the digits of N is :
  • 10
  • 11
  • 12
  • 13
+ View Answer
  • Answer
  • a) 10
  • Solution
  • Clearly, (2272 - 875) = 1397, is exactly divisible by N.
    Now, 1397 = 11 * 127
    The required 3-digit number is 127, the sum of whose digits is 10.

The difference of the squares of two consecutive even integers is divisible by which of the following integers ?
  • 3
  • 4
  • 6
  • 7
+ View Answer
  • Answer
  • b) 4
  • Solution
  • Let the two consecutive even integers be 2n and (2n + 2). Then,
    (2n + 2)² - (2n)² = (2n + 2 + 2n) (2n + 2 - 2n)
    = 2(4n + 2) = 4(2n + 1), which is divisible by 4.
