Question

8x3+12x2y+6xy2-7y3 factorised it​

Answer 1

ANSWER

Given :-

Baichung’s father is 26 years younger than Baichung’s grandfather and 29 years older than Baichung. The sum of the ages of all the three is 135 years.

To Find :-

Age of each

Solution :-

Let the age of Baichung be B

Age of father = B + 26

Age of grandfather = B + 26 + 29

Age of grandfather = B + 55

Now

(B) + (B + 26) + (B + 55) = 135

3B + 81 = 135

3B = 135 - 81

3B = 54

B = 54/3

B = 18

Now

Age of Baichung = 18 years

Age of his father = 18 + 26 = 44 years

Age of grandfather = 18 + 55 = 73 years
