Answer 1

Answer:

Age of Advika = 21 years

Step-by-step explanation:

Given :

Average age of Shikha and her husband Amit = 48 years

Average age of Shikha , Amit and their daughter Advika

= 39 years

To find :

The age of Advika

Concept :

To find the age of Advika subtract the total age of Shikha and Amit from total age of Shikha , Amit and Advika .

So , the equation will be like this -:

$\boxed{\sf{A=(39\times3)years-(48\times2)years}}$

Where,

A = Age of Advika

Solution :

$:\implies\sf{A=(39\times3)years-(48\times2)years}$

$:\implies\sf{A=117years-96years}$

$:\implies\sf{A=21years}$

So , the age of Advika is 21 years .
