Question
__________ is capable of taking decisions on its own.
Solution
The correct answer is B
If (a + b) = 1 and (1/a) – 2b = 5/a then find the value of a2 + b2.

(x + 4) 2 + (y – 1) 2 + (z + 2) 2 = 0, then find the value of 2x - 3y + z.
- If (x - y) = 4, then find the value of (x³ - y³ - 12xy).
If 70% of ‘y’ is 25% more than 30% of 140, then value of ‘y’ is:

- If p = 40 - q - r and pq + r(p + q) = 400, then find the value of (p² + q² + r²).
If (x 4 Â + x 2 y 2 Â + y 4 ) = 216 and (x 2 Â - xy + y 2 ) = 12, then find the value ...
If p = 28 - q - r and pq + r(q + p) = 182, then find the value of (p² + q² + r²).
If x + y + z = 30, x² + Y² + z² = 460 and x z = y², then find the value of x z?
