Answer:
In this particular type of question, express the number of students selected for essay writing and the total number of students from each of the two schools in fraction . Then we need to compare the fractions for finding the desired answer.
Complete step-by-step answer:
Number of students selected from school A = 250 out of 650
The number of students selected from school A expressed in fraction = 250650=513250650=513
Number of students selected from school B = 300 out of 750
The number of students selected from school B expressed in fraction = 300750=25300750=25
On comparison ,
LCM of 13 and 5 = 65
Therefore 513513 can also be written as 5×565=25655×565=2565
And 2525 can also be written as 2×1365=26652×1365=2665
And clearly , 2665>2565
