please do fastt​

Answer 1

Answer: 12 years .

Step-by-step explanation:

Let manoj's present age be x .

Then manoj's age 4 years ago = (x - 4)

Manoj's age 12 years from now = (x + 12)

So by the problem , (x + 12) = 3(x - 4)

=> x + 12 = 3x - 12

=> 2x = 24

=> x = 12 .

So Manoj's present age is 12 years .

Answer 2

Answer:

12 yrs.

Step-by-step explanation:

Let the present age of Manoj be x yrs.

4 yrs. ago.,

Age of Manoj = (x-4) yrs.

12 yrs. hence,

Age of Manoj = (x+12) yrs.

But, according to question

After 12 yrs Manoj will be 3 times as old as he was 4 yrs. ago.

Therefore, the equation formed is,

=> 3(x-4) = (x+12)

Solving the equation, we get,

=> 3x - 12 = x + 12

=> 3x - x = 12 + 12

=> 2x = 24

=> x = 24/2

=> x = 12

Hence, present age of Manoj is 12 yrs.
