Average score of the students from village B = 60
Step-by-step explanation:
90 students in a class,
From Village A = (70/100)90 = 63 Students
from Village B = 90 - 63 = 27 Students
Let say Average of Village A = X
Then Average of Class B = X + (20/100)X = 1.2X
Total Marks = 63X + 27(1.2X) = 95.4X
average score of all the students is 53
-> Total Score = 90 * 53 = 4770
=> 95.4X = 4770
=> X = 50
1.2X = 1.2 * 50 = 60
average score of the students from village B = 60
