Question

After 12 years.i shall be 3 times as old as i 4years ago. find my present age

Answer 1

Hey friend!!

let x be your present age.4 years ago, your age will be x-4. And, after 12 years your age will be x+12

It's given that, your age after 12 years is 3 times the age 4years ago

→x+12=3(x-4)

x+12=3x-12

2x=24

x=12

So, your present age will be 12 years

I hope this will help you :)

Answer 2

let my present age be = X
After 12 years:
my age = X+12

4years ago;
my age was = x-4(3 times as old as)

•x+12 =3(x-4)
X+12=3x-12
x-3x=-12-12
-2x=-24
X=24/1
X=12
•hence my age is 12 years.
