Question
A plot has to be divided among P, Q and R in the ratio
3:5:7 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.Ā ĀSolution
Let the area of plot received by P, Q and R be 3x, 5x and 7x respectively. According to the question,  => 5x + 4200 = 7x => 2x = 4200 => x = 4200/2 = 2100 Area of plot received by P and Q together, = 3x + 5x = 8x = 8 x 2100 = 16800m²
If sinā“ x + cosā“ x = 5/8, then the value of sin2x is
