the answer must be 30 but checking by calculating 15 is wrong. The answer= (225x30)/30=30

you should all think a bit(mine answer is also gicen wrong) and read the question properly , I THINK WE SHOULD TRY TO FIND OUT THE NO. OF TILES BY TAKING HCF OF 225 AND 30 . REASONS1)BECAUSE THE CHAPTER IS ABOUT NO. CALCULATION , NOT MENSURATION2) YOU DO NOT HAVE A DEFINITE METHOD BY FIRST FINDING THE AREA AND THEN DOING ALL THESE THINGS . THIS METHOD DOES NOT MAKE SENSEso , first of all , we should try out with hcf best of luck!

But they asked how many tilesThe side of one tile is 15cmso if you divide 225x30 (area of the floor)by 15x15 ( area of one tile) you get 30 so 30 is the answer

I agree to Arjit. It should be 15 because 225 is not divisible by 30

found the solution! the answer is correctif we find hcf of 225 and 30 , WE ARE FINDING OUT THE LENGTH OF ONE SIDE OF A TILE , NOT THE NO. OF TILESTHEN , WE FIND THE AREA OF ONE TILE , THAT IS 15*15=225NOW, DIVIDE THE AREA OF PLOT BY AREA OF ONE TILE .YOU WILL GET THE ANSWER I.E 30

the answer should be 30. the side of one tile is 15 cm ,but they have asked the tile so it should be 30 only . and those who say that children who are having the answer30 have no brains they only don't have brains
