Question

the ratio of father age to that of his son is 4:1 if the sum of their age is 60 find their ages
Class 7

Answer 1

Answer:

Hey Army!

$...$

Let the main ratio be x

Hence

Father's age = 4x

Son's age = x

ATQ,

Given, sum of the ages = 60 years

= 4x + x = 60

= 5x = 60

= x = 60/5

= x = 12

Hence, son's age is 12 years

Father's age = 4x = 4 × 12 = 48 years

Hope that helps!

Answer 2

Answer:

Hence the age of son and father is 12 years and 48 years respectively.

Step-by-step explanation:

As per the data provided in the given question.

The given data is as follows,

The ratio of father age and son age is 4:1 and the sum of their age is 60.

We have to find the age of son and father.

Let, we will take father age is 4x and the son age is x as below,

$Father\;age=4x\\Son\;age=x$

At first, we will find the age of the son i.e. (x).

We know that the sum of age is 60, further we get

$4x+x=60$

We know that the same variable values are .added

So we get,

$5x=60$

Now we will shift the numerator 5 of LHS to the denominator of RHS.

Further, we get

$x=\frac{60}{5}\\x=12$

The value of x is 12 hence the age of a son is 12 years.

Now we will find the father age.

We know that,

$Father\;age =4x$

Now we will substitute the value x in above formula.

$=4\times12\\=48\;years$

Hence the age of son and father is 12 years and 48 years respectively.
