Domain of f(x) = log10(log10(1 + x3)) is -

Maths-General

  1. [0, straight infinity)    
  2. R    
  3. R+    
  4. None of these    

    Answer:The correct answer is: R+because log10
    (1 + x3) > 0 Take antilog
    1+ x3 > 1 Error converting from MathML to accessible text. x3 > 0 therefore x > 0
    element of (0, straight infinity) or x element of R+

    The number of five-digit telephone numbers which can be formed using the digits 0, 1, 2 ….9 is 105 . The number of five-digit telephone number which have none of their digits repeated is 10P5 = 30240. Thus, the required number of telephone number is 105 – 30240 = 69760.

    Number of ways in which 25 identical balls can be distributed among Ram, Shyam, Sunder and Ghanshyam such that atleast 1, 2, 3, and 4 balls are given to Ram, Shyam, Sunder and Ghanshyam respectively, is-

    First of all select 1 + 2 + 3 + 4 = 10 balls out of 25 identical balls and distribute them as desired. It can happen only in one way. Now let x1, x2, x3 and x4 balls are given to them respectively.
    (where x1, x2, x3, x4 greater or equal than 0)
    Its now one can get any number of balls
    therefore non negative integral solution of
    x1 + x2 + x3 + x4 = 15
    will be the number of ways so
    15 + 4 –1C4–1 = 18C3
