Maths Simple Equation 1)A father is 30 years older than his son .In 12...
Given Information:
Let the present age of the son be x years.
The father is 30 years older than his son, so his present age is x + 30 years.
In 12 years, the man will be three times as old as his son.
Step-by-Step Solution:
Step 1: Set up the equation using the given information.
According to the given information, in 12 years, the man's age will be three times the son's age.
So, the equation can be written as:
(x + 30) + 12 = 3(x + 12)
Step 2: Simplify the equation.
Simplifying the equation, we get:
x + 42 = 3x + 36
Step 3: Subtract x from both sides.
Subtracting x from both sides, we get:
42 = 2x + 36
Step 4: Subtract 36 from both sides.
Subtracting 36 from both sides, we get:
6 = 2x
Step 5: Divide both sides by 2.
Dividing both sides by 2, we get:
x = 3
Step 6: Find the present ages.
The son's present age is x = 3 years.
The father's present age is x + 30 = 3 + 30 = 33 years.
Final Answer:
The present age of the son is 3 years, and the present age of the father is 33 years.
Let the present age of the son be x years.
The father is 30 years older than his son, so his present age is x + 30 years.
In 12 years, the man will be three times as old as his son.
Step-by-Step Solution:
Step 1: Set up the equation using the given information.
According to the given information, in 12 years, the man's age will be three times the son's age.
So, the equation can be written as:
(x + 30) + 12 = 3(x + 12)
Step 2: Simplify the equation.
Simplifying the equation, we get:
x + 42 = 3x + 36
Step 3: Subtract x from both sides.
Subtracting x from both sides, we get:
42 = 2x + 36
Step 4: Subtract 36 from both sides.
Subtracting 36 from both sides, we get:
6 = 2x
Step 5: Divide both sides by 2.
Dividing both sides by 2, we get:
x = 3
Step 6: Find the present ages.
The son's present age is x = 3 years.
The father's present age is x + 30 = 3 + 30 = 33 years.
Final Answer:
The present age of the son is 3 years, and the present age of the father is 33 years.
