Q:

# As per the National Forestry Report, 1998 , India must retain a true cover of 33 per cent as against the 19 per cent at present . A budgetary allocation of Rs 850 crore is just a drop in the ocean.Conclusions:I. The forest coverage in a country should be in proportion to its popullation II. Inadequate budgetary allocation comes in the way of enhancing the forest coverage.

 A) If only conclusion I follows B) If only conclusion II follows C) If neither I nor II follows D) If both I and II follow

Answer:   B) If only conclusion II follows

Explanation:

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.

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.  $\inline \fn_jvn \small 5a^{2}-18a+9=0$

2.  $\inline \fn_jvn \small 3b^{2}+5b-2=0$

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

Answer & Explanation Answer: D) a > b

Explanation:

1. $\fn_jvn \small 5a^{2}-18a+9=0$

$\fn_jvn \small 5a^{2}-15a-3a+9=0$

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

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

a = 3 or 3/5

2. $\inline \fn_jvn \small 3b^{2}+5b-2=0$

$\inline \fn_jvn \small 3b^{2}+6b-b-2=0$

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 clesr 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.
