after 12 years manoj will be 3times as old as he was 4 years ago. find his present age
Given, Age of manoj after 12 years = 3 × Age of Manoj 4 years ago
(x + 12 ) = 3 (x – 4)
x + 12 = 3x – 12
x -x + 12 = 3x-x -12
12 = 2x -12
12 + 12 = 2x -12 + 12
2x = 24
2x/2 = 24/2
x = 12
Thus, present age of manoj is 12 years.
Check:
12+12=24
3(12-4)=3*8=24
So answer is correct.

To find Manoj's present age, we can use algebra.
Let's assume Manoj's present age is x.
According to the given information, after 12 years, Manoj will be 3 times as old as he was 4 years ago. This can be written as:
x + 12 = 3(x - 4)
Now, let's solve this equation to find the value of x.
x + 12 = 3x - 12 [Using the distributive property]
12 + 12 = 3x - x
Simplifying further:
24 = 2x
Dividing both sides by 2:
x = 12
Therefore, Manoj's present age is 12 years old.
