In a word, the position of a particular letter L is 5th from the left side and 6th from the right hand side. How many letters must be eliminated to make it a 7 letter words. |
|
Answer» It is given that:
To FinD:
How to solve? We have the position of L from left side as well as right side. So, to get the position we can simply ADD them but if we do so, then the position of L will be added two times. We can hence, subtract 1 from the sum. ✤ A total no. of persons in a row = Position of a person from L.H.S + Position of the same person from R.H.S – 1. ⇒ Total no. of persons = 5 + 6 - 1 ⇒ Total no. of persons = 10 We need to eliminate letters to get a 7 letter word. ⇒ No. of letters to be eliminated = 10 - 7 = 3 (Ans) And we are done! :D Explore more!!
