Answer 1

Answer:

Let Prachi's age be x

Therefore Prachi's brother's age = x-3

Prachi's mother is 3 times older than her and 4 times older than her brother

Therefore as per question

x ×3 =( x-3) × 4

or 3x = 4x - 12

or 3x - 4x = -12

or - x = -12

or x = 12

Prachi's age = 12

Prachi's brother's age = 12-3

= 9

Prachi's mother's age = 12×3

= 36

Answer 2

HEY MATE YOUR ANSWER IS HERE...

→ LET PRACHI'S AGE BE = X YEARS

→ SO HER BROTHER'S AGE =( X - 3) YEARS

( AS HE IS 3 YEARS SMALLER THAN PRACHI )

→ AGE OF PRACHI'S MOTHER = 3X yrs

★ NOW ACCORDING TO THE QUESTION ★

PRACHI'S MOTHER IS 4 TIME OLDER THEN HER BROTHER

HENCE ,

3X = 4 ( X - 3 )

3X = 4X - 12

X = 12

HENCE PRACHI'S AGE = 12 yrs

HER BROTHER'S AGE = 12 -3 = 9 yrs

AND HER MOTHER'S AGE = 3X = 36yrs

THANKS FOR YOUR QUESTION HOPE THIS HELPS
