I don't know whether it is right but the answer what I got is Rs 225.10. I got by finding the area of both rectangles and changed into centimetre. And I divided them and the answer is 10. As 1 tile is Rs 22.50 then 10 tiles is 225.10

Marble tile
length=12 cm
breadth=10cm

area of a rectangle =l x b
=12 x 10
=120cm

area of the wall = 4 x 3
=12m

1m=100cm
12m=12x100=1200cm

1200 divided by 120
=10
therefore, 10 tiles
 
one tile cost rupees 22.50
so,10 tiles cost=
10 x 22.50
=225/-
