Question
A plot has to be divided among P, Q and R in the ratio
2:5:8 respectively. If the area of plot received by R is 4200m² more than the area of plot received by Q, then find the total area of plot received by P and Q. ÂSolution
Let the area of plot received by P, Q and R be 2x, 5x and 8x respectively. According to the question,  => 5x + 4200 = 8x => 3x = 4200 => x = 4200/3 = 1400 Area of plot received by P and Q together, = 2x + 5x = 7x = 7 x 1400 = 9800m²
(x + 1)2 + (y – 3) 2 + (z + 5) 2 = 0, then find the value of 2x + 3y - z.
If p = 36 - q - r and pq + r(q + p) = 310, then find the value of (p² + q² + r²).
If x + 1/x = 3, find the value of x³ + 1/x³.
