If the number 42573 * is exactly divisible by 72, then the minimum value is * is:
  • 4
  • 5
  • 6
  • 7
  • 8
+ View Answer
  • Answer
  • c) 6
  • Solution
  • 72 = 9 * 8, where 9 and 8 are co-prime.
    The minimum value of x for which 73x is divisible by 8 is, x=6.
    Sum of digits in 425736 = (4 + 2 + 5 + 7 + 3 + 6) = 27, which is divisible by 9.
    Required value of * is 6.

If x and y are the two digits of the number 653 xy such that this number is divisible by 80, then x+y = ?
  • 2
  • 3
  • 4
  • 6
  • None Of These
+ View Answer
  • Answer
  • a) 2
  • Solution
  • 80 = 2 * 5 * 8.
    Since 653 xy is divisible by 2 and 5 both, so y = 0. Now, 653 x0 is divisible by 8, so 3x0 should be divisible by 8.
    This happens when x = 2.
    x + y = (2 + 0) = 2.

If the product 4864 * 9 P 2 is divisible by 12, the value of P is:
  • 2
  • 5
  • 6
  • 8
  • None Of These
+ View Answer
  • Answer
  • e) None Of These
  • Solution
  • Clearly, 4864 is divisible by 4.
    So, 9P2 must be divisible by 3. So, (9 + P + 2) must be divisible by 3.
    P = 1.

20)
If the number 5 * 2 is divisible by 6, then * = ?
  • 2
  • 3
  • 6
  • 7
+ View Answer
  • Answer
  • a) 2
  • Solution
  • 6 = 3*2. Clearly, 5*2 is divisible by 2. Replace * by x.
    Then, (5 + x + 2) must be divisible by 3.
    So, x = 2.
