Answer 1

Anu and Vinay are ranked 25th and 21st from the bottom in a class of 31 students respectively. You subtract their top ranks from the total number of students and add 1 to find their bottom ranks.option c is correct.

Step-by-step explanation:

To calculate the ranks of Anu and Vinay from the bottom in a class of 31 students, we need to subtract their ranks from the top from the total number of students and then add 1, because we include the student's position when counting from either end.

For Anu, who is ranked 7th from the top:

1. Subtract the rank from the total number of students: 31 - 7 = 24.
2. Add 1 to get the rank from the bottom: 24 + 1 = 25.

Anu's rank from the bottom is therefore the 25th.

For Vinay, who is ranked 11th from the top:

1. Subtract the rank from the total number of students: 31 - 11 = 20.
2. Add 1 to get the rank from the bottom: 20 + 1 = 21.

Vinay's rank from the bottom is therefore the 21st.

The correct answer to the question is Option C: 25th and 21st.
