Q:

# Some hills are rivers. Some rivers are desrets. All desrets are roads.Conclusions:1. Some roads are rivers2. Some roads are hills3. Some deserts are hills

 A) None follows B) Only 1 follows C) Only 1 and 2 follows D) All follow

Answer:   B) Only 1 follows

Explanation:

Some hills are  rivers. Some rivers are deserts.

Since both the premises are particular, no defenite conclusion follows.

Some rivers are deserts. All deserts are roads

Since one premise is particular,the conclusion must be particular and should'nt contain the middle term. Since it follows that 'Some rivers are roads'. 1 is the converse of this conclusion and so it holds.

Q:

In each question given below four conclusions are followed by statements. You have to take the three given statements to be true (even if they seem to be at variance from the commonly known facts). Read the conclusions and decide which of the following set of statement indicate that conclusion is logically follows.

Statements :

1. All chairs are tents.

2. No chairs is jugs.

3. No jugs is glasses.

4. No glasses is pots.

Conclusions :

I. All pots are tents.

II. All glasses are chair.

III. Some jugs are tents.

 A) Only conclusion I follows B) Both conclusion II & III follows C) None follows D) Only conclusion II follows

Answer & Explanation Answer: C) None follows

Q:

Find which of the two conclusions I and II given below is/are definitely true from the the given statements.

Statements: I > W > T > N, I = F = G = C

Conclusions:    I. W > I

II. C > N

 A) Only Conclusion I is true B) Only Conclusion II is true C) Both conclusions I & II are true D) Neither conclusion I nor II is true

Answer & Explanation Answer: B) Only Conclusion II is true

Explanation:

From the given Statements :

1. I > W > T > N

2. F = G = C

Conclusions are :

I. W > I (False)

II. C > N (True)

Q:

Study the question and all the three statements given and decide whether any information provided in the statements are redundand and can be dispensed with while answering the questions.

Question :

What is the rate of interest per year ?

Statements :

1. The amount invested is Rs. 6000.
2. The amount becomes Rs. 6741.60 in 2 years at compound interest.
3. The difference between compound interest and simple interest in 2 years is Rs. 21.60.

 A) Only 3 B) Both 2 & 3 C) Any two of (1, 2 & 3) D) None

Answer & Explanation Answer: C) Any two of (1, 2 & 3)

Explanation:

Using Both 1 & 2 statements we get the rate of interest as in (1) we have given principle amount and in (2) compound interest for 2 years. By this data we get the rate%.

Using Both 1 & 3 statements we can get the rate% as we have principle amount & difference between compound interest and simple interest in 2 years.

Using Both 2 & 3 statements we get compound interest & simple interest by which we get principle amount. So that we can calculate %rate.

Hence by using any two of the three statements(1,2&3) we get rate of interest.

Q:

In the following question, two equations numbered 1 and 2 are given. You have to solve both the equations and determine the relation between a and b.

1.  $5{a}^{2}-18a+9=0$

2.  $3{b}^{2}+5b-2=0$

 A) a >= b B) a <= b C) a < b D) a > b

Answer & Explanation Answer: D) a > b

Explanation:

From solving 1 and 2 we get,

1.

5a(a-3)-3(a-3) = 0

(5a-3)(a-3) = 0

a = 3 or 3/5

2.

3b(b+2)-1(b+2) = 0

b = -2 or b = 1/3

Here when a = 3, a > b for b = -2 and b = 1/3

when a = 3/5. a > b for b = -2 and b = 1/3.

Hence, it is clear that a > b.

Q:

Assuming the given statements to be true, find which of the two conclusions A and B given below is/are definitely true.

Statements: C < T < L= P > Q,  N > C > Y

Conclusions:   A. P > Y       B. Y < P

 A) only conclusion B is true. B) only conclusion A is true. C) neither conclusion I nor II is true. D) either conclusion I or II is true.

Answer & Explanation Answer: A) only conclusion B is true.

Explanation:

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.

Q:

Read both the statements given below and answer the question.

Q : Which train did Harish catch to go to office ?

Statements :

A. Harish missed his usual train of 4.15 p.m. A train comes in every 15 minutes.

B. Harish did not catch the 4.45 p.m. train or any train after that time.

 A) If statement B alone is sufficient but statement A alone is not sufficient. B) If statement A alone is sufficient but statement B alone is not sufficient. C) If both statement together are sufficient, but neither statement alone is sufficient. D) If statement A and B together are not sufficient.

Answer & Explanation Answer: D) If statement A and B together are not sufficient.

Explanation:

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.

Q:

What is the value of KL ?

Statement A: ${K}^{2}$= 4.
Statement B: L = 0.

 A) Only A is sufficient B) Only B is sufficient C) Both (A) and (B) are sufficient D) None of the above

Answer & Explanation Answer: B) Only B is sufficient

Explanation:

From statement B,

As the value of L = 0, the value of KL = 0.

Hence only statement B is sufficient.
