Question

Reena’s mother’s age is 3 less than 3 times Reena’s age. If her mother’s age is 57, find Reena’s age.​

Answer 1

We do not know sunita’s age.

Let us take it to be y years. .

Sunita’s mother’s age is 3years older than 3y;

It is also given that Sunita’s mother is 36 years old.

Therefore, 3y+3=36

Subract 3 from both side

3y+3−3=36−3

3y=33

Divide both side by 3

y=11

Answer 2

Step-by-step explanation:

Let Reena's age be x and her mother's age be 3x-3

ATQ

3x-3=57

3x=57+3

3x=60

x=20

Reena's age=20years
