From (1)&(2), the birthday falls on February 20 or 21.

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) 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 even in both the statements together are not sufficient to answer the question |

Explanation:

Statement I is merely an interpretation of the information contained in the question

However, Vipin's salary can be determined from statement II as follows

Let Vipin's and Javed's salaries be 4x and ax respectively.

Then, 3x = 4500 or x = 1500 Vipin's salary = 4x = Rs 6000.

Thus, II alone is sufficient.

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 even in both the statements together are not sufficient to answer the question |

From statements I and II together, we can conclude only that either B is the sister or brother of A.

So, even from both the statements, the exact relation cannot be known.

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 even in both the statements together are not sufficient to answer the question |

Explanation:

Comparing the information in the question with statement 1. we find that '2' and '9' are the codes for 'tie' and 'dip'. So, '7' represents 'button'.

Thus, I alone iS sufficient.

Again, comparing the information in the question with II, WO find that the common code number '7' stands for the common word 'button'.

Thus, II alone also is sufficient.

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 even in both the statements together are not sufficient to answer the question |

Explanation:

Comparing the information in the question with I. we find that 'tin' and 'lee' are the codes for 'always' and 'keep'.

So. 'pee' represents 'smiling' Thus, I alone is sufficient Am.

comparing the information in the question with II, we find that the common code word 'pee' stands for the common word 'smiling'.

Thus, II alone is also sufficient

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 even in both the statements together are not sufficient to answer the question |

Explanation:

From the two statements, we find that maximum (243 x 3) i.e, 729 visitors saw the exhibition, But the exact number cannot be determined
