5 years ago, Bharti's mother was 3 times as old as
Bharti. After 6 years she will be twice as old as Bharti.
Present age (in years) of Bharti is​

Answer 1

Step-by-step explanation:

LET THE PRESENT AGE OF BHARTI BE X

LET THE PRESENT AGE OF BHARTI'S MOTHER BE Y

5 years ago

bharti's age=x-5

bharti's mother age=y-5

therefore, 3( x-5)=y-5. (1)

6 years later

bharti's age=x+6

bharti's mother age=y+6

therefore, 2(x+6)=y+6. (2)

from (1) and (2)

3x-15=y-5. (1)

3x-y-10=0

2x+12=y+6 (2)

2x-y+6

solving the above equation

3x-y-10=0

2x-y+6=0

x=16. y=38

bharti's present age is 16

bharti's mother present age is 38
