Question
How many persons are there between X and
U? Study the following information carefully and answer the question given below: There are Eleven people T, U, V, W, X, Y, Z, A, B, C and D are living in a 11 floor building on different floors from top to bottom (such as ground floor is numbered as 1 and top floor is numbered as 11) but not necessarily in the same order. T live above Y. B live above X but not immediately. X does not live immediately above or immediately below V. Z lives on 7th floor. Two person live between Z and A. W live immediately above A. There is as many person living above W as below U. Five persons live between Y and D, who lives below Z. Only one person live between Z and V. C lives below V.Solution
1. Z lives on 7th floor. 2. Two person live between Z and A. 3. W live immediately above A. 
4. There is as many person living living above W as below U. 
There is no floor empty for U in CASE2 so CASE2 is cancelled out. 5. T live above Y. 6. Five persons live between Y and D, who lives below Z. 
7. Only one person live between Z and V. 8. B live above X but not immediately. 9. X does not live immediately above or immediately below V. 
If 27 (x+y)³ − 8(x−y)³ = (x + 5y) (Ax² + By² + Cxy), then what is the value of (A+B-C)?
If a + b + c = 5, a³ + b³ + c³ = 85 and abc =25, then find the value of a² + b² + c² – ab –bc – ca
