JEE · Math · previous-year question
- A.$${46^{th}}$$
- B.$${59^{th}}$$
- C.$${52^{nd}}$$
- D.$${58^{th}}$$correct
Answer
D. $${58^{th}}$$
Explanation
Clearly, number of words start with $$A = {{4!} \over {2!}} = 12$$ Number of words start with $$L = 4! = 24$$ Number of words start with $$M = {{4!} \over {2!}} = 12$$ Number of words start with $$SA = {{3!} \over {2!}} = 3$$ Number of words start with $$SL = 3! = 6$$ Note that, next word will be "SMALL" Hence, the position of word "SMALL" is 58th.
