The correct usage is: One of the
problems.
In cases of the form, “One of + the + Noun(Plural)”, the noun is
always plural.
The correct sentence should be: One of the
problems with you is that you are not sincere.
In the same way, note the proper use of nouns after the following phrases,
Each of + the + Noun (Plural noun should be used) e.g. Each of the boys
Similarly, Either of + the + Noun (Plural) Neither of + the + Noun (Plural)e.g. Either of the girls | Most of + the + Noun | 1. If Noun is Uncountable, use Singular form of noun e.g. Most of the time
2. If Noun is Countable, use plural form of noun e.g. Most of the visitors |
None of + the + Noun (Plural) e.g. None of the boys
Any of + the + Noun (should be Plural) - Only if Noun=Countable
e.g. Any of these three girls | All of + the + Noun | 1. If Noun is Uncountable, use Singular form of noun e.g. All of the luggage
2. If Noun is Countable, use plural form of noun e.g. All of the coins |
Let us now see the proper application of apostrophe ( 's )
Man/animal - man's life, ram's wife, dogs' kennels, cows' tails |
Time - a moment's delay, a week's leave, a month's absence |

Space - a razor's edge, a needle's point, a boat's length. |

Special cases - The ship's arrival/departure, The train's arrival/departure, The plane's arrival/departure, A boat's crew |
Note: I) Apostrophe ('s) is not used with two immediate/consecutive nouns.e.g. Rachit's wife's career
– incorrect.The correct usage is - The career of Rachit's wife
II) In case of compound nouns, apostrophe ('s) is used with tailing word.e.g. Son-in-
law's shirt
The Government of
India's order
