Answers
Answer:
answer,
baichung's age = 17 yr
baichung's father's age = 46 yr
baichung's grand father age = 72
Step-by-step explanation:
baichung's age =x
baichung's father's age= baichung's grand father age -26
x+29=baichung's grand father age -26
x+29+26= b.g.f
x+55=b.g.f
baichung's grand father age = x + 55
given ,
x+29+x+55=135
3x+84 =135
3x=135-84
3x=51
x=51/3
x=17
therefore,
baichung's age=17 yr
baichung's father's age= 46 yr
baichung's grand father age= 72 yr
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
