A) If the data in statement I alone are sufficient to answer the question | B) If the data in statement II alone are sufficient answer the question |

C) If the data either in I or II alone are sufficient to answer the question; | D) If the data in both the statements together are needed. |

Explanation:

From I. we have A <B< D.

From II. we have C < B

Combining( I) and (II), we can conclude that D is the heaviest

So. both the statements are needed

A) If the data in statement I alone are sufficient to answer the question | B) If the data in statement II alone are sufficient answer the question |

C) If the data either in I or II alone are sufficient to answer the question; | D) If the data in both the statements together are needed. |

Explanation:

II reveals that the previous bus had left al 7.45 p.m

C) If the data either in I or II alone are sufficient to answer the question; | D) If the data even in both the statements together are not sufficient to answer the question |

Explanation:

The present price of the mixer can he calculated from statement II as follows

Let the earlier price be Rs x.

Then, 10% of x = 220 or x = 2200. Present price = Rs (2200 + 220) = Rs 2420.

So, only II is needed.

A) January | B) February |

C) March | D) August |

Explanation:

We know that the day repeats after every seven days.

Given that first day of the month is Tuesday

i.e 1st - Tuesday

1+7 = 8 - Tuesday

8+7 =15- Tuesday

15+7=22-Tuesday

22+7=29-Tuesday

But given that last day of the same month is Monday

It is possible only in he month of Febuary with 28 days.

A) II only | B) II and III together |

C) I and II together ( | D) I, II and III together |

Explanation:

From III, we have : Rajan's basic salary = Rs 1550.

From I, we have : Vasu's basic salary = Rs (1550 + 100) = Rs 1650.

From II. we have : Rajan's other allowances = RS 2000

and Vasu's other allowances = Rs 2050.

Vasu's monthly salary is (1650 + 2050) = Rs 3700.

Thus, all the three statements are required.

A) I and 11 only | B) I, II and III together |

C) II and III together | D) I, II and III together are not sufficient |

Explanation:

The information given in the three statements together is also not sufficient to answer the given question.
