C
Let the option A is correct. Then sum of 2's will be 96 (48*2) so remaining sum will be 124 - 96 = 30. This can not be completed by 24's so eliminate it.

If B then sum of 2's = 70. Remaining sum = 54 this can not be completed by 24's. eiminate it.

if C then sum of 2's = 76 remaining sum = 48 which is clearly competed by using 24's two times. hence this is the answer.I don't even bothered to check option D and E.

Even I picked C. But the OA is given as E.

So lets wait for some more responses.

Actually if you plug in numbers and see you will realize that both C and E are right....not sure what I'm missing??
