Question
Statements:Â Some designations are
descriptions Some descriptions are securities No security is a position Conclusion: I. Only descriptions is designations II. No designation is a description In each of the questions below are given some statements followed by some Conclusions. You have to take the given statements to be true even, if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.ÂSolution
Some designations are descriptions (I) → Conversion → Some descriptions are designations (I). Hence neither conclusion I nor II follow.
If a + b + c = 14 and ab + bc + ca = 60, then find the value of a² + b² + c².
If x = (2+√3)/(2-√3), y = (2-√3)/(2+√3). Then find out the value of (x²+y²-xy)/(x²+y²+xy)?
If p = 24 - q - r and pq + r(q + p) = 132, then find the value of (p² + q² + r²).

If (4x + 3y): (28x - y) = 1: 5, then what is the value of (3x 2 Â + 4y 2 ): (7x 2 Â + 2y 2 )?
Simplify:
7x + 9y - [(14x + 5y) - (5x + 3y) + 4y] - 5x(123×123×123 + 130×130×130)/(123×123 - 123×130 + 130×130) = ?Â
