Correct Answer: if the data either in Statement I alone or in Statement II alone are sufficient to answer the question.
Explanation:
From I: The possible day of exam is Wednesday.
From II. The third day of the week is Wednesday.
Hence, either statement I alone or statement II alone is sufficient.
Correct Answer: if the data in Statements II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question. if
Explanation:
From I: Possible months: January, February, March, April, May or June.
From II: Rahul's son correctly remembers that his father went on vacation after 31st March but before 1st May. So, his father went on vacation in the month of April. Hence only II is sufficient.
Correct Answer:
Explanation:
From I: P > Q, but T is not the tallest.
From II: R > P, but S is not the tallest.
From I and II: R > P > Q. Neither S nor T can be the tallest. Hence R is the tallest.
Correct Answer: if the data in Statements II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.
Explanation:
From I: EAST or ETSA
Hence I alone is not sufficient
From II: Only EAST is possible
Hence II alone is sufficient.
Correct Answer: if the data given in both the Statement I and II together are not sufficient to answer the question.
Explanation:
Even by using both the statements, we are not able to detemine who is tallest as we do not have the exact idea about the height of Q.
Correct Answer: if statement II alone is sufficient to answer the question.
Explanation:
It is given that Ram got a dividend of ? 1500.
Statement I
Knowing the dividend paid last year, we cannot find the dividend paid this year.
Statement II
Given that Ram bought 350 shares of face value ? 10, and so, their total face value is ?3500. So, here we know the investment and the return hence wen can find out the rate of interest.
Correct Answer: if both statement I and II together are not sufficient to answer the question.
Explanation:
Statement I is not sufficient as the size of the ice cube and height of the container is not known hence statement I is not sufficient alone.
Statement I is not sufficient as the dimension of the container is not known.
We cannot answer the question even by combining both the statement as the height of the container is not known.
Correct Answer: if statement I alone is sufficient to answer the question.
Explanation:
Since sum is 360 hence P + Q + R + S = 360
From statement I alone we will get P = (Q + R + S)/3 from this we can find the value of P hence statement I alone is sufficient enough.
From statement II alone we can not find the value of P.
Correct Answer: if statement II alone is sufficient to answer the question.
Explanation:
Let the 7 consecutive whole numbers be (n ± 3), (n ± 2), (n ± 1), n.
Now i we consider Statement I alone
Product of these 7 integers = 702800
Since 702800 = 24 52 (251)(7), it cannot be the product of 7 consecutive whole numbers. Hence I alone is insufficient.
Now if we consider Statement II alone
Given that their sum = 105 = 7n or n = 15 and then 7 consecutive integers are 12, 13, 14, 15, 16, 17, 18 So, II alone is sufficient.
Correct Answer: if statement II alone is sufficient to answer the question.
Explanation:
If we look at Statement I
It is given that the circle are concentric. But nothing is given about their dimensions. Hence I alone is not sufficient.
In statement II ratio of area is given hence we can find the required ratio.
