if we consider the production cost of both TV(colour and B.W.) are same then it can solved as follows---
let BW=x , colour=315-x (consider 1 rs PC per tv)
x{(100-6)/100}+(315-x){(100+15)/100} = 315+315*(9/100)
on solving we get
x=90

by using allegation
b&w color
-6 15
9
(15-9) (-6-9)
6 15
i.e 2 5
so 7 ratio is 315
so 2 ratio=90
so no of black and white set is=90
