Answer 1

Answer:

✏Given:

• After 12 years, I shall be 3 times as old as I was 4 years ago

✎To Find:

• The present age.

$\dag \: \huge{\underline{\mathtt{\red{S}\pink{o}\green{l}\blue{u}\purple{t}\orange{i}\green{o}\bold\red{n}}}} \gray↷$

Let, the present age be X years.

~After 12 years my age will be (X+12) years.

∴ X + 12 = 3 ( x - 4 )

$\blue\implies x + 12 = 3x - 12$

$\blue\implies x - 3x = - 12 - 12$

$\blue\implies - 2x = - 24$

$\blue\implies \frac{ - 2x}{ - 2} = \frac{ - 24}{ - 2}$

$\blue\implies x \red{ = } \green{12}$

Therefore, the Present age is $\large \underline \mathtt \pink{12 \: years.}$
