students were selected?
Answers
Answer:
Number of students selected from school A = 250 out of 650 The number of students selected from school A 250 5 expressed in fraction = 650 13 Number of students selected from school B = 300 out of 750 The number of students selected from school B 2 300 expressed in fraction = 750 5 On comparison, LCM of 13 and 5 = 65 Therefore can also be written as
5 Therefore 13 can also be written as 5 x 5 65 = 25 65 2 And can also be written as 5 2 x 13 65 26 65 25 26 And clearly, 65> 65 Therefore school B has more students selected. Note- We need to remember that the number of students does not directly tell which school has more selected students. Note that this question could also be done by finding the percentage of students got selected in each of the schools.
