Question

the present age of the father is 45 and his son age is 20. find the ratio of the age of the son to the sum of all ages in simplest form is:-

a. 13:4
b. 4:15
c. 15:4
d. 4:13​

Answer 1

Answer:

the age of father is 45

the age of son is 20

then,

the ratio is = 45:20

= 45/20

= 9:4

Answer 2

Answer :-

• Option d) is correct.

• The ratio of the age of the son to the sum of all ages in simplest form is 4 : 13.

Given :-

• The present age of the father is 45.

• His son's age is 20.

To find :-

• The ratio of the age of the son to the sum of all ages in simplest form.

Step-by-step explanation :-

• In this question, it has been given that the present age of the father is 45 while his son's present age is 20. We have to find the ratio of the age of the son to the sum of all ages in simplest form. But for that, we first have to find the sum of all ages because it has not been given to us in the question, and then we can find out our ratio.

Calculations :-

• Age of the father = 45.
• Age of the son = 20.

• So, the sum of their ages = 45 + 20 = 65.

• Now, since we know the sum of the ages, therefore we can find the ratio.

-----------------------------------------------------------

Final answer :-

Ratio of the age of the son to the sum of all ages :-

$\sf \dfrac{20}{65}$

Reducing the numbers,

$\sf \dfrac{4}{13} = 4 : 13.$

Hence, the required ratio is 4 : 13.
