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.  

A 16800m² Correct Answer Incorrect Answer
B 12000m² Correct Answer Incorrect Answer
C 17000m² Correct Answer Incorrect Answer
D 11200m² Correct Answer Incorrect Answer
E 9800m² Correct Answer Incorrect Answer

Solution

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
