Question

the present age of Arun father is three times that of Arun after 5 years sum of their ages would be 70 find their present ages​

Answer 1

Answer:

Let the present age of Arun be x.

Present age of Arun's father = 3x

According to Question,

x+5+3x+5 = 70

=> 4x+10 = 70

=> 4x = 70-10

=> 4x = 60

=> x = 60/4

=> x = 15

Hence, present age of Arun = 15 years

Present age of father = (3×15) years = 45 years

Answer 2

${ \red{ \bf{YOUR \: QUESTION}}}$

The present age of Arun father is three times that of Arun after 5 years sum of their ages would be 70. Find their present ages.

${ \green{ \bf{REQUIRED \: ANSWER}}}$

Arun present age = 15 years

Arun's father present age = 45 years

Step by step explanation:-

$\mathbb{Let \: arun \: age \: be \: x }$

$\mathbb{ Arun's \: father \: present \: age \: be \: 45}$

$After \: 5 \: years \: Arun \: age = \: \: (x+5)$

$Arun's \: father \: age \: after \: 5 \: years \: =(3x+5)$

$\pink{So, According \: to \: Question:-}$

$\pink{(x+5)+(3x+5)=70}$

$4x + 10 = 70 \\ 4x = 60 \\ x = 15$

Therefore, Arun Father present age =15 years

Arun present age =15×3=45

After 5 years Arun age = 15+5=20

After 5 years Arun's father age = 45+5=50
