Direction: Each of the questions below consists of a question and two statements numbered I and II given
below it. You must decide whether the information provided in the statements is sufficient to answer the
question. Consider the following while answering the questions:
• Mark 1 as the answer, if the question can be answered by using one of the statements alone but
cannot be answered using the other statement alone.
• Mark 2 as the answer, if the question can be answered by using either statement alone.
• Mark 3 as the answer, if the question can be answered by using both statements together but
cannot be answered using either statement alone.
• Mark 4 as the answer, if the question cannot be answered even by using both statements together.

Answers
Answer:
1. D
2. C
3. C
4. D
5. D
Explanation:
1. Since, we don't know the quantity that one cup can store, we can't predict the orange juice in liters, even after using both statements.
2. First statement clearly shows that, Z's value is in between X and Y
The second statement makes it more clear that Y is smaller than X.
so the order of consecutive integers is like X>Z>Y.
Hence we can predict the highest integer.
3. Using both statements we can predict that there are three 1 ₹ coins and two 50 paisa coins
So, 3*1₹ +2*0.5 ₹ = 4₹
also 3>2.
So C is correct option.
4. Since the price for Tin is not given, makes it harder to predict the cost of Cu per kg.
Even after using both statements, we can't, so D
5. D option
suggestions are welcomed
please correct me if I'm wrong
Answer:
1. d
2. c
3. c
4. d
5. d
Explanation:
1. We don't know how many cups makeup 1 liter.
2. Average of X and Y is Z. Means they can be in the order either X<Z<Y or Y<Z<X. And given X is greater than Y. So, the order is Y<Z<X.
So we need both statements to determine the highest.
3. possibilities:
50paise 1 rupee
0 4
2 3
4 2
6 1
8 0
statement 1: two possibilities (0,4) (2,3)
statement 2: total of 5 coins means (2,3)
So, both statements are needed.
4. We are not given the cost of tin per Kg. So we cannot answer.
5. Average=sum of all scores/ no.of scores
We do not know how the values are distributed between the highest and lowest scores. Ex: (880,890,2100,2390) or (880,1999,2380,2390)
So, the average cannot be predicted.
