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

Answer: Option  C Explanation:A + C = D + E ==> C - E = D - A  ...(i)
B + 2C = D + 2E ==> 2C - 2E = D - B ==> C - E = D - B⁄2   ...(ii)
From (i) and (ii) we get : D - A = D - B⁄2 ==> 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. ```

4.  If A + D > C + E, C + D = 2B and B + E > C = D, it necessarily follows that

B + D > C + E
A + B > 2D
A + D > B + E
A + D > B + C

```Answer

Answer: Option  D Explanation:B + E > C + D, C + D = 2B ==> B + E > 2B ==> E > B.
A + D > C + E, E > B ==> A + D > C + B. ```
