Solution

As it is given that every member know at least one language.
And number of prsons knowing Hindi $= n (H) = 100$
number of prsons knowing Urdu $= n (U) = 50$
number of prsons knowing both $= n (H \cap U) = 25$
Hence $n (H U U) = n (H) + n (U) - n (H \cap U) = 100 + 50 - 25 = 125$
Hence the total number of members = 125
