Answer 2

$\bigstar$ EXPLAINATION $\bigstar$

• Procedure

Let Manu's age be x

Therefore,

Manu's father age is 3x + 3

But,

In the question they gave Manu's father age = 36 years old

Therefore,

3x + 3 = 36

3x = 33

x = 11 years old

$\boxed{Answer\:is\:11\:years}$

• Extra Information

$\implies$ Formulas related to Algebra

$(a + b)² = a² + b² + 2ab$

$(a - b)² = a² + b² - 2ab$

$(a + b)(a - b) = a² - b²$

$(a + b)³ = a³ + b³ + 3a²b + 3ab²$

$(a - b) = a³ - b³ - 3a²b + 3ab²$

$a³ + b³ = (a + b)(a² + b² - ab)$

$a³ - b³ = (a + b)(a² + b² + ab)$
