Answer: 4 years
Explanation Step 1: Let's denote the age of the youngest child as x. The ages of the 5 children will be x, x + 3, x + 6, x + 9, and x + 12. Step 2: Calculate the sum of their ages. x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50 Step 3: Simplify the equation. 5x + 30 = 50 Step 4: Solve for x. 5x = 20 x = 4

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: 2430
Explanation Number of pens produced in February = 3000 - 10% Number of pens produced in February = 3000 - 30= 2700 pens Number of pens produced in March is 2700 - 10% of 2700 Number of pens produced in March = 2700 - 270= 2430 pens
Answer: 25 days
