Explanation

Sum the students in standard I for all schools: 42 (A) + 50 (B) + 40 (C) + 45 (D) + 48 (E) + 52 (F) = 277. Dividing the total 277 by 6 schools gives approximately 46.16, which rounds to 46.

AI explanation

The number of students in standard I across the six schools are 42, 50, 40, 45, 48 and 52. The total number of students in standard I is 42 + 50 + 40 + 45 + 48 + 52 = 277. Dividing this sum by 6 gives an average of 277 / 6, which is approximately 46.16. This rounds to an approximate average of 46 students.
