A + B = C + DB + D > A + CA > B Now, B + D > A + C and A > B ⇒ B + D > A + C > B + CB + D > B + C So, D > C Now, B + D > A + C ⇒ B + D = A + C + K Also , A + B = C + D ⇒ B -D = C - A ⇒ 2 B = 2C + K B > C A> B> C & D > C Clearly, each one of A, D, and B has more amount than C.Hence,C has the least amount.
