Answer 1

Answer:

age of is sum 3 fraction ×5

Answer 2

Age of Rahul is 84 years.

The age of the Son is 42 years.

GIVEN: Rahul spent one-sixth of his life as a boy. one-twelfth as a youngster and one-seventh as a bachelor. Five years hence, a son was born. When the son's age is half the measure of Rahul's life. Rahul fell. After surviving for four years, his life ended.
TO FIND Age of Rahul and son.
SOLUTION:
Let us assume that,

Rahul's age is x.

Son's age is y.

According to the question we are given,

The son's age is half the measure of Rahul's life.

Therefore,

y = x/2

x = 2y                                                                                ----Eq1

Also, it is given that Rahul spent his entire life in different phases. This can be written in the form of an equation.

x/6+x/12+x/7+5+y+4 = x                                                   -----Eq2  

Now, To find the value of x

We solve both equations by replacing the value of x as 2 with

Using equation1 and 2.

2y/6+2y/12+2y/7+5+y+4 = 2y

y/3+y/6+2y/7+y+9 = 2y

14y+7y+12y+42y+278 = 2y

              42

75y+378 = 84y

378 = 9y

42 = y

Putting this value of y in Equation1

x = 2y

x = 2(42)

x = 84

Therefore,

Age of Rahul is 84 years.

The age of Son is 42 years.
