Q 4:Find the smallest number y such that y×162 is a perfect cube.
(A) 24
(B) 27
(C) 32
(D) 36
Ans: (D) 36

Q 5: The probability that a k-digit number does NOT contain the digits 0,5 or 9 is
(A) 0.3k
(B) 0.6k
(C) 0.7k
(D) 0.9k
Ans: (C) 0.7k
Solution: Total possibilities =9×10k−1, because most significant digit has 9 options (excluding 0) and every other digit has 10 options from 0 to 9.
Possibility of not containing any of the digits 0,5,9=7k, as now every digit has 7 options.
Required probability =7k / (9×10k−1) = (0.7)k

(C) 4
(D) Cannot be determined
Ans: (A) 2
Solution:
- There are at least two men and two women
- None of the women are right-handed and There are at least three right-handed persons means atleast 3 right handed persons are men
- So atleast 3 Men and 2 Women are there
- Remaining 1 person can be Man or woman with condition “Woman with left handed or Man with either left handed or right handed.”
Case-1: Let us suppose that a person is a woman. So, 3 Right handed Men and 3 Left Handed Women which is not possible
Case-2: Let us suppose that a person is a Left handed man. So, 3 Right handed Men and 2 Left Handed Women and 1 left handed man
Case-3: Let us suppose that a person is a Right handed man. So, 4 Right handed Men and 2 Left Handed Women, which is also not possible
So 2 women are there
