Answer 1

Answer:

Present age of Muskan is 8

Present age of Nita is 23

Step-by-step explanation:

Let the present age of Muskan be $x$

present age of Nita is $31-x$

3 years ago

age of Muskan is $x-3$

age of Nita is  $31-x-3$

                       $=28-3$

given that age of Nita 3 years ago is four times the age of Muskan

according to the question age of Nita is  $4(x-3)$

$28-x=4(x-3)\\28-x=4x-12\\28+12=4x+x\\5x=40\\x=\frac{40}{5} \\=8$

therefore

the present age of Muskan is 8

the present age of Nita is

                       $31-x\\31-8\\23$
