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:

I. $\inline \fn_jvn \small a^{2}-7a+12 =0$,

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

Solve both the equations to find the values of a and b  ?

 A) if a > b B) if a < b C) if the relationship between a and b cannot be established. D) if a ≤ b

Explanation:

I.  (a - 3)(a - 4) = 0

=> a = 3, 4

II.   (b - 2)(b - 1) = 0

=> b = 1, 2

=> a > b

which one should be used to calculate the age ?

A) mother/son = Non-prime number
B) mother/son = Perfect square number

 A) only A alone is sufficient B) only B alone is sufficient C) both A and B are required D) Cannot be answered

Explanation:

For the given problem there are three possiblities.
Father's age can be = 36, 31, 29

Q:

Fact 1: All hats have brims.
Fact 2: There are black hats and blue hats.
Fact 3: Baseball caps are hats.

If the first three statements are facts, which of the following statements must also be a fact?
I. All caps have brims.
II. Some baseball caps are blue.
III. Baseball caps have no brims.

 A) I only B) II only C) I, II, and III D) None of the statements is a fact.

Answer & Explanation Answer: D) None of the statements is a fact.

Explanation:

All baseball caps have brims, since baseball caps are hats (Fact 3) and all hats have brims (Fact 1). This rules out statement III—but it doesn’t follow that all caps, a category that may include caps that are not baseball caps, have brims (statement I). Statement II cannot be confirmed, either, since it is possible, given the information, that all baseball caps are black.
