Question

Arun's age 13 years ago is half his age 13 years later. Find his present age

Answer 1

Answer:

Let his present age be x.

Thus,His age 13 year ago is x-13

His age after 13 year is x+13

Step-by-step explanation:

According to the question,

• x-13=x+13/2
• 2x-26=x+13
• X=13+26
• X=39

Therefore,Arun's present age is 39 years.

Answer 2

Answer:

Step-by-step explanation:

Let the present age of Arun is x .

Before 13 years his age = ( x - 13 ) years

After  13 years his age = ( x + 13 ) years.

According to the given question ,

Age of Arun before 13 years = 1/2 * Age of Arun after 13 years .

x - 13 = 1/2 * x + 13

x - 13 = x + 13 / 2

2 ( x - 13 ) = x + 13

2x - 26 = x + 13

2x - x = 13 + 26

x = 39 years.

Therefore,

Arun's present age is 39 years.
