A) A | B) B |

C) C | D) D |

Explanation:

D _ C _ A --------(1)

D > B > C --------(2)

from (1) and (2)

D > B > C > A ---------(3)

Again E _ B _ A

But B > A, from (3)

So E > D > B > C > A [ Since B is the average of E and A so it is eqidistant from both E and A]

A) 34 | B) 36 |

C) 35 | D) 37 |

A) Rs. 3748 | B) Rs. 3847 |
