Answer: 1.5 : 1
Explanation:
The average of 92 marks for the test is a weighted average of the proportion of students in the class.
Assume boys are in the proportion, x.
(90 * x) + (95 * (1 - x)) = 92
90x + 95 - 95x = 92
-5x = 92 - 95
-5x = -3
x = -3/-5
x = 0.6
Boys are 0.6 of the class
Girls are:
= 1 - 0.6
= 0.4
0.6 : 0.4
1.5 : 1
