Answer the next 3 Questions.
Comprehension:
Read the following information and answer the following questions.
Bindu is standing exactly in the middle of a line of girls. Asha is 6th to the left of Bindu and Ritu is 16th to Bindu's right.
SubQuestion No: 1
What is Asha's position in the line?
The problem describes the relative positions of three girls in a line: Bindu, Asha, and Ritu. Bindu is in the exact middle. We are given Asha's position relative to Bindu and Ritu's position relative to Bindu. To find Asha's position in the line, we need to first determine Bindu's position, which is the middle position. Since Bindu is in the middle, the number of girls to her left must be equal to the number of girls to her right. We can use Ritu's position to find the number of girls to Bindu's right, and then use that information to find Bindu's position and subsequently Asha's position.
Thus, Asha is at the 11th position in the line.
D) 11 — As calculated, Asha's position is 11th in the line.
SubQuestion No: 2
What should be the minimum number of girls in the line?
SubQuestion No: 3

The question asks to fill in the blank in the trigonometric identity: \(\sin A = \text{_____} \times \cos A\). To solve this, we need to recall the fundamental trigonometric ratios and their relationships, specifically the definition of \(\tan A\).
B) tan A is the correct option because, by definition, \(\tan A = \frac{\sin A}{\cos A}\), which implies \(\sin A = \tan A \times \cos A\).
