2.  If A + C = D + E, B + 2C = D + 2E, C - E > E - B and 2C > A + D, then


D > B > C > A > E
A > B > C > D > E
D > C > A > E > B
C > B > E > D > A


Answer

 Option

A + C = D + E ==> C - E = D - A ...(i) B + 2C = D + 2E ==> 2C - 2E = D - B ==> C - E = D - B2 ...(ii) From (i) and (ii) we get : D - A = D - B2 ==> D - B > D - A ==> -B > -A ==> B < A. B + 2C = D + 2E, 2C > A + D ==> B + A + D < D + 2E ==> B + A < 2E Now, B + A < 2E, B < A ==>A > E, E >B ...(iii) A + C = D + E, A > E ==>C < D ==> D > C ...(iv) 2C > A + D, C < D ==> C > A. ....(v) From (iii), (iv) and (v) we have : D > C > A > E > B.
