Q) In a seminar , the numbers of participants in English , German and Sanskrit are 45, 75 and 135. Find the numbers of rooms required to house them , if in each room the same number of participants are to be accommodated and they should be of the same language 1) 45 2) 17 3) 75 4) 135

$$\implies$$ Total number of rooms required for English = $$\frac{45}{15}$$ = 3
$$implies$$ Total number of rooms required for German = $$\frac{75}{15}$$ = 5
$$\implies$$ Total number of rooms required for sanskrit = $$\frac{135}{15}$$ = 9
$$\implies$$ = Total number of rooms = $$3 + 5 + 9 = 17$$
