Step-by-step explanation:

Geeta planned to floor her living room of size 5m*3m with least no. Of square tiles. If the cost of 1st 100 tiles is rs. 64 per tile, next 100 tiles is rs. 50 per tile, and rs 40 per tile after 1st 200 tiles. Find the total cost of tiling​

To have least number of tiles

we can have tile of size 1m * 1m

as HCF of 5 & 3 = 1

Then Only 15 tiles are required

& cost = 64 * 15 = Rs 960
