if the data in statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question;

Q2. Which of the four numbers w, x, y and z is the largest ?
I. The average of w, x, y and z is 25.
II. The numbers w, x and y are each less than 24.

if the data in statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question;

if the data in statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question;

if the data either in statement I or in Statement II alone are sufficient to answer the question;

if the data even in both statements I and II together are not sufficient to answer the question;

if the data in both statements I and II together are necessary to answer the question.

Solution:

From I,
w + x + y + z = 4 × 25 = 100
From II,
x, y, w < 24
And if average of all of 4 numbers is 25 then z must be greater than 25
So, by combining both statements, we can find that z is the largest no.

Q3. What is the average weight of the three new members who are recently included into the team?
I. The average weight of the team increases by 20 kg.
II. The three new men substitute earlier members whose weights are 64 kg, 75 kg and 66 kg.

if the data in statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question;

if the data in statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question;

if the data either in statement I or in Statement II alone are sufficient to answer the question;

if the data even in both statements I and II together are not sufficient to answer the question;

if the data in both statements I and II together are necessary to answer the question.

Solution:

Let total no. of members initially was n and original average of their weight was x.
Combining statements I and II,
nx – 64 – 75 – 66 + a + b + c = (x + 20) × n where a, b and c are the weights of three new members
⇒ (a + b + c) = 20n + 205
Here, we don’t know value of n.
So, answer can’t be found.

Q10. What will be the cost of painting the four walls of a room if the rate of painting is Rs 25 per square metre?
A. Perimeter of the floor is 44 m.
B. Height of the wall of the room is 10 m.
C. Ratio of length and breadth of the room is 3 : 1.

None

Only C

Any two of them

Either B or C

Question can’t be answered even after using all the information

Solution:

From (A) and (B)
Area of four walls of the room = 2 (l + b) × h = 44 × 10 = 440 m²
So, required cost = 440 × 25 = Rs 11000
Hence, statement C can be dispensed with.
