Q1. Using the empirical relation, if the mean is 20 and the median is 14, the mode is:
- A.2
- B.8
- C.34
- D.32
Answer: A. 2
Q2. Using the empirical relation, if the mean is 20 and the median is 23, the mode is:
- A.29
- B.43
- C.14
- D.26
Answer: A. 29
Q3. Using the empirical relation, if the mean is 23 and the median is 20, the mode is:
- A.17
- B.43
- C.29
- D.14
Answer: D. 14
Given 23, 20, asked for the unknown. By substitute the standard values sin 30 = 1/2, sin 45 = 1/sqrt 2, sin 60 = sqrt 3/2, cos 30 = sqrt 3/2, cos 60 = 1/2, tan 45 = 1. substitute the standard values sin 30 = 1/2, sin 45 = 1/sqrt 2, sin 60 = sqrt 3/2, cos 30 = sqrt 3/2, cos 60 = 1/2, tan 45 = 1 → hence the value = 14. perform the arithmetic in the given expression. Therefore option D) 14. Others fail: option A) '17' is incorrect: Wrong: a common multi-step slip gives this; option B) '43' doesn't hold - Wrong: uses an incorrect intermediate value.
