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
