Question

Five years ago,Jeeshan's age was half of the age he will be in 8 years. How old is he now?

Answer 1

Answer :-

• Present age of Jeeshan = 18 years.

Explanation :-

Given :

• Five years ago, Jeeshan's age was half of the age he will be in 8 years.

To Find :

• Present Age of Jeeshan.

Solution :

Let the Present age of Jeeshan be x years.

Five years ago, age of Jeeshan = x - 5 years.

Eight years from now, age of Jeeshan = x + 8 years.

According to the Question,

➞ x - 5 = (x + 8)/2.

➞ 2(x - 5) = x + 8.

➞ 2x - 10 = x + 8.

➞ 2x - x = 8 + 10.

➞ x = 18.

Therefore,

Present age of Jeeshan = 18 years.

Answer 2

Answer:

$\large ❀ \bf\red {\underline{Given}}❀$

• Five years ago,Jeeshan's age was half of the age he will be in 8 years.

$\large ❀ \bf\red {\underline{To\:find}}❀$

• How old is he now.

$\large ❀ \bf\red {\underline{Solution}}❀$

Let, John's age is now x years

• 5 years ago, he was ( x-5 ) years old

• In 8 years , he will be ( x+8 ) years old

$\\ \large \bf \color{violet}{now \: according \: to \: the \: question} \\ \\ \\ \\ \large \bf{\green{x - 5 }= \frac{1}{2}(x + 8) } \\ \\ \\ \large \red\implies \bf{\green{2(x - 5) }= x + 8} \\ \\ \\ \large \red\implies \bf{\green{2x - 10} = x + 8} \\ \\ \\ \large \red\implies \bf {\green{2x - x} = 8 + 10} \\ \\ \\ \large \red\implies \bigstar \: \bf\green{x = 18} \bigstar$

$\large \therefore \bf\color {orange}{he \: is \: 18 \: years \: old \: now}$
