Question
Who among A, B, C, D and E is exactly in the middle when
they are arranged in ascending order of their heights? I. D is taller than B but shorter than E. II. C is taller than B and E but shorter than A. Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. Read both the statements and Give answer:Solution
From I. E > D > B Hence data in statement I alone is not sufficient to answer the question. From II. C > B, C > E, A > C. Hence data in statement II alone is not sufficient to answer the question. From I and II. A > C > E > D > B E is in the middle. Hence data in both statement I and II together are necessary to answer the question.

If a + b + c = 12 and ab + bc + ca = 47, and a, b, c are real numbers, find the value of a³ + b³ + c³ − 3abc.
If a + `1/b` = 1 and b + `1/c` =1 , then the value of c + `1/a` is
