    Answer:Sara hina and Arslan Have RS79.4,RS 72.4 and RS238.2 respectively.

    Step-by-step explanation:

    Step 1

    Let the amount that hina has be x

    the amount that sara has be represented as  7+x

    and the amount that Arslan have be represented as 3(7+x)

    such that the total amount in their wallet which is 390 can be expressed as

    x+7+x + 3(7+x)=390

    Step 2

    Solving

    x+7+x +21+3x=390

    5x+28=390

    5x==390-28

    x=362/5=72.4

    Hina has RS 72.4

    Sara =7+x==72.4+77= RS 79.4

    Arslan =3(7+x)=3 x 79.4=RS 238.2
