As the flooring is done in the pattern involving red, blue, green and white, hence the flooring is done with a group of four tiles.
Now, we know that the pattern repeats itself after four terms.
As the tiles starts with red and if it ended with white then total tiles can be written as a multiple of 4, that is ,4I.
Since, it ends with green so total tiles will be 4I + 3.
Thus, among the options the only value which on dividing by 4 leaves a remainder as 3 is 35
Ans. (B)
