Answer 1

Step-by-step explanation:

Let Sahil present age of = x

since ,Sahil mother's age is three times his age.

Sahil mother present age = 3x

after 5 years,

Sahil age = x + 5

Sahil mother,s age = 3x + 5

According to question,

x + 5 + 3x + 5 = 66

4x + 10 = 66

4x = 66-10

4x = 56

x = 56/4

x = 14

Sahil present age = 14 years.

Sahil mother's present age = 3*14 = 42 years.

Let Baunching father age = x

According to question,

Baunching grandfather age = x+26

Baunching age = x - 29

sum of their ages = 135

x + x+26 + x-29 = 135

3x -3 = 135

3x = 135 + 3

3x = 138

x = 138 / 3

x = 46

baunching father age = X = 46 years.

baunching grandfather age = X + 26

= 46+26 = 72 years.

Baunching age = x-29 = 46 - 29 = 17 years.

Let present age of RAVI = X years.

after 15 years Ravi age = x + 15

According to question,

x + 15 = 4x

4x - x = 15

3x = 15

x = 5

Present age of Ravi = 5 years.
