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:

'59' means Injurious habit' and '157' means 'stop bad habit' (from I). Thus, the common code number '5' stands for common word 'habit'. So. '9' represents 'injurious'.Hence, I is sufficient.

Also, '59' means Injurious habit' and '839' means 'smoking is injurious'. Thus, the common code number '9' stands for common word 'injurious'. So, '5' represents 'habit'. Thus, II is also sufficient.

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 I, we find that the weight of one pole is (5 x 4) = 20 kg ,and so the weight of 10 poles is 200 kg.

Thus, I alone is sufficient.

From II. we have : (weight of 3 poles — weight of 2 poles) -= 20 kg or weight of one pole - 20 kg.

So. weight of 10 poles 200 kg.

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 |

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 : D > A , D> C,

From II, we have : E >B > D.

Combining the above two, we get : E > B> D> (A and C).

So, E is the tallest.

Clearly, both the statements are needed to answer the question

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, P > M, P > K, A > P.

From II we have, M > K, P > M, A > P.

Combining the above two, we have : A > P > M > K.

Thus, Akash is the heaviest. So, both the statements are required.
