From statement B,
As the value of L = 0, the value of KL = 0.
Hence only statement B is sufficient.
From statement A, we know that Pipe A can fill the tank in 40 hours. However, this information is not sufficient as we do not have the data for Pipe B. Hence, statement A alone cannot answer the given question.
From statement B, we know that Pipe B is one third as efficient as pipe A. However, we do not know the rate at which Pipe A fills the tank. Hence, we will not be able to find the rate at which Pipe B fills the cistern. Therefore, statement B alone is not sufficient to answer the question.
Now, if we combine the two statements, we know that Pipe A take 40 hours to fill the cistern.
Pipe B takes 120 hours to fill the cistern.
If they worked alternately, then either Pipe A could have started the cycle or Pipe B could have started the cycle.
If Pipe A started the sequence of filling alternately, then at the end of two hours, the two pipes together would have filled 1/40 + 1/120 = 1/30 th of the tank in an hour. Or the cistern will fill in 30 hours.
If Pipe B started the sequence, then at the end of 2 hours, the two pipes together would have filled 1/120 + 1/40 = 1/30 th of the tank in an hour. Or the cistern will fill in 30 hours.
As the answer obtained irrespective of which pipe started the sequence is the same, the correct answer is (3) - i.e., both the statement are sufficient to answer the question.
There is no indication that Indian scientists are incapable of developing enzymes. There could be any number of reasons why Indian scientists used Russian enzymes.
So conclusion A does not follow.
In addition, cost is not discussed in the passage at all. There is no mention of a correlation between cost and extraction of proteins.
Thus, conclusion B does not follow either.
All baseball caps have brims, since baseball caps are hats (Fact 3) and all hats have brims (Fact 1). This rules out statement III?but it doesn?t follow that all caps, a category that may include caps that are not baseball caps, have brims (statement I). Statement II cannot be confirmed, either, since it is possible, given the information, that all baseball caps are black.
The statement mentions that chances of heart ailments are greatly reduced by a regular half-hour exercise. So, a follows. However, it talks of only reducing the probability which does not mean that persons involved in sedentary jobs shall definitely suffer from heart ailments. So, b does not follow.
Hence, concusion a only follows the given statement.
Fall of demand of gold is due to rising prices. Hence, I can be concluded. II cannot be concluded from the given statement.
From both statements we cannot conclude the train catched by Harish
Since he missed at 4.15 and train coes at 4.30, 4.45, 5.00,...
But in B given that he didn't catch the train at 4.45 and after that.
So both statements A & B together are not sufficient to answer the question.
From given statements, we can conclude that
N > C < T < L= P > Q .....(1)
Here given that C > Y but in eq(1) we got that C < T < T <= P => Y is definitely less than P.
So only conclusion B is True.
The relation of forest to population can't be derived from the statement. Hence I does not follow. From the second sentence and from the tone of the statement II can be derived. Hence follows.
Since half of the four children are girls, two must be boys. It is not clear which children have blue or brown eyes. So only statement (b) follows.
All locks are bangles + All bangles are cars = A + A = A
= All locks are cars => Some cars are locks.
Hence conclusion (a) follows.
All keys are locks + All locks are bangles = A + A = A
= All keys are bangles => some bangles are keys.
Hence conclusion (b) follows.
All keys are bangles + All bangles are cars = A + A = A
= All keys are cars => Some cars are keys.
Hence conclusion (C) follows.
Thus all a, b and c follows.
