Question

baichung,s father is 26 years younger than baichung,s grandfather and 29 years older than baichung .the sum of ages of all three is 135 years .what is the age of each of them​

Answer 1

Answer:

age of Baichung is 17 years

age of Baichung's father is 46 years

age of Baichung's grandfather is 72 years.

Step-by-step explanation:

let the age of Baichung be x years.

age of father would be x + 29 years.

age of grandfather would be x + 29 + 26  = x + 55 years

now sum of their ages is given to be 135 years.

so,

x + x + 29 + x + 55 = 135

3x + 84= 135

3x = 135 - 84

3x = 51

x = 51/3

x = 17

age of Baichung = 17 years

age of Baichung's father = 17 + 29 = 46 years

age of Baichung's grandfather = 17 + 55 = 72 years.

Answer 2

Let the age of Baichung’s father be x.

Then, the age of Baichung’s grandfather = (x+26)

and, Age of Baichung = (x-29)

According to the question,

x + (x+26) + (x-29) = 135

⇒ 3x + 26 – 29 = 135

⇒ 3x – 3 = 135

⇒ 3x = 135 + 3

⇒ 3x = 138

⇒ x = 138/3

⇒ x = 46

Age of Baichung’s father = x = 46

Age of Baichung’s grandfather = (x+26) = 46 + 26 = 72

Age of Baichung = (x-29) = 46 – 29 = 17
