Answer: 209
Explanation x + y = 30 ... (Equation 1) x - y = 8 ... (Equation 2) We can solve these equations by adding them together, which eliminates y: 2x = 38 Dividing both sides by 2 gives us: x = 19 Now that we have x, we can find y by substituting x into Equation 1: 19 + y = 30 Subtracting 19 from both sides gives us: y = 11 Now that we have both x and y, we can find their product: Product = x * y = 19 * 11 = 209
Answer: 5
Explanation Let 45 x A = (25 x 900)/100 ∴ A = (25 x 9)/45 = 5

Answer: 10
Explanation Let C's age be x years. Then, B's age = 2x years. A's age = (2x + 2) years. ∴ (2x + 2) + 2x + x = 27 ⇒ 5x = 25 ⇒ x = 5. Hence, B's age = 2x = 10 years.
Answer: 21
Explanation To find the number of good apples , you can subtract the number of bad apples from the total number of apples. First, calculate the number of bad apples : 2/9 of 27 = (2/9) × 27 = 6 So, there are 6 bad apples. To find the number of good apples , subtract the bad apples from the total: 27 - 6 = 21 Therefore, there are 21 good apples.
Answer: x +2
