E. 5,20
pls. explain in detail.
hi
this is a derangement question. Basically we need to de-arrange the 4 keys. if all 4 keys goes in correct lock then the fifth key will automatically go into the correct lock.
so the minimum number is 4.
for the maximum number consider cases
so if you want to de arrange 1 thing you can do it in 0 ways. Incase of 2, you can do it in 1 way. put 1 wrong key in wrong lock. In case of 3 you can do it in 2 ways such that no key goes into the correct lock. similarly for 4 its 9 ways. now the 10 one will be the one where the keys of 4 lock matches the correct lock. since 4 are matched the 5th key will be matched itself.
hope it helps !!!
Only those who object question gets increment or all will get based on revised answer key?
