Question

Baichung’s father is 26 years younger than Baichung’s grandfather and 29 years older
than Baichung. The sum of their ages is 135. Find their ages

Answer 1

Answer:

let baichungs age be =x

therefore his baichungs father's age= x+29

therefore baichungs grandfathers age= x+29+26+x

sum of their ages =135

so

x+29+26+x=135

2x+55=135

2x=135-55

2x=80

x=40

so father's age =40+29=69

and grandfathers age=95

Answer 2

Answer :-

Their ages are,

• Baichung's is 17 years
• Baichung's father is 46 years
• Baichung's grandfather is 72 years.

Step-by-step explanation :-

To Find,

• The ages of Baichung, Baichung's father and Baichung's grandfather.

Solution,

Given that,

• Baichung’s father is 26 years younger than Baichung’s grandfather and 29 years older
• than Baichung
• The sum of their ages = 135

Let us assume,

• Baichung's age as x
• Baichung's father as x + 29
• Baichung's grandfather age as ( x + 29 ) + 26 or x + 55

Therefore,

➮ x + x + 19 + x + 55 = 135

➮ 3x + 19 + 55 = 135

➮ 3x + 84 = 135

➮ 3x = 135 - 84

➮ 3x = 51

➮ x = 51 / 3

➮ x = 17 ★

Hence, the value of x is 17.

Now, the ages are,

• Baichung's age

➮ x

➮ 17 years ★

• Baichung's father age

➮ x + 29

➮ 17 + 29

➮ 46 years ★

• Baichung's grandfather age

➮ x + 55

➮ 17 + 55

➮ 72 years ★

Hence, the ages of Baichung's is 17 years, Baichung's father is 46 years and Baichung's grandfather is 72 years.
