• Option : C
• Explanation : Let weight of 1Oth student = x kg
Average weight of 9 students = 60 kg
total weight of 9 students = 9 x 60 = 540 kg
Now, Average weight of 10 students
= (540 + x)/10
According to the question,
x - (540 + x)/10 = 9
1Ox - 540 - x = 90
9x = 90 + 540 = 630
x = 630/9 = 70 kg

• Option : A
• Explanation : Observe the classical square of opposition below:

If A proposition is true, E proposition-which is its contrary-- is false, O proposition- which is its contradictory-- is false; and I proposition-which is its subaltern-is true.

• Option : B
• Explanation : Classroom teaching is a planned procedure carried out by the teacher who is ideally in complete control of its direction and progress. It means that the teacher also has control over the self (conduct, approach, attitude, etc.), the mode of communication and method of delivery of the lesson to be transacted.

• Option : C
• Explanation : If the assessment procedure is rigid about the language, mode, means and method of the assessment and promotes certain culture specific values; it is biased against those who may be comfortable with different ones. So, if assessment procedures are flexible and diverse to make disadvantaged students comfortable, it doesn't contribute to assessment bias.
