Q10. If B > X and A >= D are definitely true, what will come in the place of blank spaces in the given expression?
W = X __ Y <= A __ B __ C >= D
1) < , = , >= 2) > , = , >= 3) <= , = , >= 4) >= , = , >= 5) Other than given optionsAnswer & Explanation
Second highest number = 746;
746/2 = 373
Third highest number = 519.
Difference = 519 – 373 = 146
519 = 915;
328 = 823;
746 = 647;
495 = 594;
837 = 738;
Lowest number = 594
519 = 951;
328 = 832;
746 = 674;
495 = 549;
837 = 783
Highest number = 951 or 519
- 5;From I, ‘a’ is a prime number. But a unique value of a is not known, a can be 2, 3, 5, 7……… Hence, statement I
alone is not sufficient. From II, again a unique value of a
is not known, a can be 2, 4,6…Hence statement II alone is not sufficient. Combining I and II, that ‘a’ is even and
prime. Hence, I and II together are sufficient to answer
- 4; From I and II, we get 2 equation in two variables. But
they are dependent. Thus, eventually we get one equation in two variables, which have infinite solution set.
- 1; Check option by pick method.
1) W = X < Y <= A = B >= C >= D
