Answer 1

Answer:

Given :

$\textsf{Ramu 's father is three times that the age of Ramu}$

$\textsf{After 5 years sum of their age is 70 years }$

To find :

$\textsf{The present age }$

Concept :

Let their ages be x

So ,

Ramu 's age = (x+5)

Ramu 's father age = (3x+5)

So , to find their present age use this equation -:

$\sf\boxed{x+5+3x+5=70}$

After that the value of x will come that will be the age of Ramu . And to find the age of Ramu 's father multiply it with 3 .

Solution :

$\sf:\implies{x+5+3x+5=70}$

$\sf:\implies{x+3x+5+5=70}$

$\sf:\implies{4x+10=70}$

$\sf:\implies{4x=70-10}$

$\sf:\implies{4x=60}$

$\sf:\implies{x=\dfrac{60}{4}}$

$\sf:\implies{x=15}$

So , the age of Ramu is 15 years

Age of Ramu 's father -:

$\sf:\implies{15\times3}$

$\sf:\implies{45\:years}$

So , the age of Ramu 's father is 45 years .

Answer :

Present age of Ramu = 15 years

Present age of Ramu 's father = 45 years ...
