Answer» Answer: Step-by-step explanation: Let the present age of Aftab = x And, present age of his DAUGHTER is REPRESENTED as = y Seven years ago, Aftab’s age = x – 7 Age of Aftab’s daughter = y – 7 According to the question, (x – 7) = 7 (y – 7 ) x – 7 = 7 y – 49 x – 7Y = – 49 + 7 x – 7y = – 42 … (i) x = 7y – 42 Putting y = 5, 6 and 7, we GET x = 7 × 5 – 42 = 35 – 42 = – 7 x = 7 × 6 – 42 = 42 – 42 = 0 x = 7 × 7 – 42 = 49 – 42 = 7
Three years from now, Aftab’s age = x + 3 Age of Aftab’s daughter = y + 3 According to the question, (x + 3) = 3 (y + 3) x + 3 = 3y + 9 x – 3y = 9 – 3 x – 3y = 6 … (ii) x = 3y + 6 Putting, y = – 2, –1 and 0, we get x = 3 × – 2 + 6 = – 6 + 6 =0 x = 3 × – 1 + 6 = – 3 + 6 = 3 x = 3 × 0 + 6 = 0 + 6 = 6

The cost of plastering the 4 walls of a room which is 4m high and breadth one third of its length is Rs. 640 at the rate of Rs. 5/m². What will be the cost of carpeting its floor at the rate of Rs. 250/m². |
|
Answer» Step-by-step explanation: The area of the 4 WALLS is then 3x^2 + 3X^2 + 3X^2/2 +3X^2/2 = 9X^2 If the cost of PLASTERING is R5/sq m, then 9X^2 × 5 = 720 Solving this gives X = 4 m - a RATHER HIGH ceiling The floor area is then (3×4) × (3×4/2) = 72 sq m Carpeting is then 250×72 = R18000 |
