Answer 2

Convert units:

12m = 1200 cm

10m = 1000cm

-

Number of tiles needed length-wise:

number of tiles = 1200 ÷ 25 = 48 tiles

-

Number of tiles needed breadth-wise:

number of tiles = 1000 ÷ 10 = 100 tiles

-

Find total tiles needed:

Total tiles = 100 x 48 = 4800

-

Find cost:

1 tile = Rs 8

4800 tiles = 8 x 4800 = Rs 38400

-

Answer: Rs 38400
