Answer:
To find Manoj's present age, we can follow these steps: 1. Let's assume Manoj's present age is represented by the variable "M". 2. Four years ago, Manoj's age would have been M - 4. 3. After 12 years, Manoj's age will be M + 12. 4. According to the given information, after 12 years, Manoj will be 3 times as old as he was 4 years ago. Mathematically, this can be represented as M + 12 = 3(M - 4). 5. Simplifying the equation, we have M + 12 = 3M - 12. 6. Subtracting M from both sides of the equation, we get 12 = 2M - 12. 7. Adding 12 to both sides of the equation, we have 24 = 2M. 8. Dividing both sides of the equation by 2, we find that M = 12. Therefore, Manoj's present age is 12 years. I hope this explanation helps you understand how to find Manoj's present age. If you have any further questions, feel free to ask.
