Answer 1

Correct Question :

Prabhat’s age is 5 years more than five times the age of his son. Find the age of his son. If his age is 40

〜> Prabhat's age can't be 57 years more than five times the son's age.

Answer:

Son's age = 7 years

Step-by-step explanation:

To find:

Age of his son.

Assumption:

Assuming the age to be x.

and

Son's age to be y.

Procedure:

☞ Prabhat's age is 5 years more than five times his son's age.

Equation formed :

$\bold{ \implies\: 5y + 5x = x}$

☞ Prabhat's age is 40 years now.

Equation formed :

$\bold{5y + 5 = 30}$

☞ Subtracting -5 from both the sides.

$\bf \implies \: 5y + 5 - 5 = 40 - 5$

$\bf \implies5y = 35$

☞ Dividing 5 from both the sides.

$\bf\implies \dfrac{5y}{5} = \dfrac{35}{5}$

$\bf \implies y = 7years$

Y = Son's age = 7years

Answer 2

Αɳʂɯҽɾ :—

Let the Son's age be x years.

Prabhat's age = 40 years

Also,

Prabhat's age = 5x + 5 years

So,

5x + 5 = 40

5x = 40 - 5

5x = 35

x = 35/5

x = 7 years

Son's age = 7 years.
