Question

the age of father is 30 years more than that of his son 5 years hence father's age will be three of his son's age find their present age

Answer 1

Answer:

Present age of son = 10 years

Present age of father = 40 years

Step-by-step explanation:

Step 1 : Define x

Let the present age be x years

Given, father is 30 years old than his son

So let the age of father be x + 30

After 5 years, age of son = x + 5 and age of father = x + 30 + 5 = x + 35

After 5 years, father will be three times the age of his son = 3{x + 5)

Step 2 : Find the value of x

3(x + 5) = x + 35

=> 3x + 15 = x + 35

=> 3x - x = 35 - 15

=> 2x = 20

=> x = 10

Step 3 : Find their present ages

Present age of son => x years

=> 10 years

Present age of father = x + 30

=> 10 + 30

=> 40 years

Answer 2

here is your answer OK ☺☺☺☺☺☺☺☺

suppose the present age of of father is x

so given question in 30 year more so (X +30)

after five year age of son (x+5)and father (x+35)

given in this question after father will be thrice of son so... 3(x+5)

so equation....

3(x+5)=x+35

3x +15 = X +35

3x-x= 35 - 15

2x = 20

X = 20/2
x= 10

present age of son = 10

so father age = X + 30 = 10 + 30 = 40


thanks for asking this question ☺☺
