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 |

Explanation:

Fall of demand of gold is due to rising prices. Hence, I can be concluded. II cannot be concluded from the given statement.

A) Only A follows | B) Only B follows |

C) Both (A) and (B) follows | D) Neither (A) nor (B) follows |

A) a >= b | B) a <= b |

C) a < b | D) a > b |

Explanation:

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 clesr that a > b.

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. |

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.

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. |

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.

A) Only A is sufficient | B) Only B is sufficient |

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

Explanation:

From statement B,

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

Hence only statement B is sufficient.
