Question

after 12 years Manoj will be 3 times as old as he was 4 years ago find his present age ​

Answer 1

Let his present age be=x
X+12=3(x-4)
X+12=3x-12
X-3x=-12-12
-2x=-24
X=24/2
Therefore,x=12

Answer 2

Answer:

Let present age of manoj be x years.

Then,majoj's age after 12years =x+12

Manoj's age 4 years ago=x-4

Acording to the question.

x+12=3x-4

taking variable to 1 side and constant at the other side

3x-x=12+4

2x=16

x=16/2

x=8

hence,manoj's present age is 8 years
