Question

Ramesh's age is 17 years. His grandfather is 4 times the age of Ramesh. His grandmother is 7 years younger than his grandfather. His father is 2 times + 4 years the age of Ramesh. And his mother is 4 years younger than his father. Tell the age of all the members.

Answer 1

Answer:

Let Baichung's age be x years. Then, Baichung's father's age =(x+29) years

Baichung's grandfather's age =[(x+29)+26) years =(x+55) years

According to the given condition, we have

x+(x+29)+(x+55)=135

⇒3x+84=135

⇒3x=135−84

⇒3x=51

⇒x=

3

51

=17

∴ Baichung's age is 17 years, his father's age is 46 years and his grandfather's age is 72 .

Answer 2

Answer:

Let Arvind's age = x

Let Arvind's father age = y

Thus, y=4x

and, y−5=7(x−5) or y=7x−30

Thus, 4x=7x−30

3x=30 or x=10

Hence, y = 40 years

Thus, age of Arvind's father is 40 years
