After 12 years manoj will be 3 times as old as he was 4 years ago. Find his present age.
Let x = present age.
Set up equation:
x+12 = 3(x-4)
Solve for x.
x=12
To find Manoj's present age, we can use algebraic equations.
Let's assume Manoj's present age is represented by 'x'. According to the problem, after 12 years, he will be 3 times as old as he was 4 years ago, which gives us the equation:
x + 12 = 3(x - 4)
To find x, we can solve this equation step by step:
First, distribute the 3 on the right side of the equation:
x + 12 = 3x - 12
Next, simplify the equation by combining like terms:
12 + 12 = 3x - x
24 = 2x
Divide both sides of the equation by 2:
x = 12
Therefore, Manoj's present age is 12 years.
