Answer 1

Ans 11)
Let Baichungs father's present age be x years
Given Baichungs father is 29 years older than Baichung
Hence Baichungs age is (x − 29) years
Baichungs grandfather is 26 years older than Baichungs father.
Hence Baichungs grandfathers age = (x + 26) years
Given sum of three ages = 135 years
∴ x + (x − 29) +(x + 26) = 135
3x − 3 = 135
3x = 135 + 3 = 138
∴ x = 46
Baichungs fathers age = 46 years
Baichungs grandfathers age = (x + 26) = (46 + 26) = 72 years
Baichung's age = (x − 29) = (46 − 29) = 17 years

Let Ravi s present age be X years.

Ravi s Age after 15 Years be : (X+15) Years

his age after 15 years will be four times his present age.

4X = (X+15)
4X - X = 15
3X = 15
X = (15/3)
X = 5.

Hence Ravi s Present age is 5 Years.

Answer 2

11.

let the baichungs father age be x

therefore baichungs grandfather age be x+26

therefore baichungs age is x-29

baichungs age+baichungs grandfather age + baichungs father age is equal to sum of there ages

x+x+26+x-29 -135

3x+26-29 - 135

3x+(-3)-135

3x - 135+3

3x - 138

X is equal to 138 divided by 3

x is equal to 46

hence father age is 46 years (x)

hence grandfather age is 72years(x+26)

hence baichungs age is 17 years(x-29)

hi!!!

ravi's present age = r

ravi's age 15 years later = r + 15 = 4r

so 15 = 4r - r

15 = 3r

15/3 = r

5 =r

so ravi's present age = 5

ravi's present age + 15 =20

20 = 4r

= 5 x 4

= 20 year
