If there are 3 alphabets in the English series between the alphabets written against numbers 10 and 22, then how many alphabets are there between the alphabets written against numbers 18 and 22?
“$k$ alphabets between” two letters means a gap of $k+1$ in positions. Use $A=1,\dots,Z=26$ for quick checks.
Four
From Q42 setup: $10\!\to\!P$, $18\!\to\!N$. “Three alphabets between 10 and 22” means the letter at 22 is 4 positions away from $P$ (16th), so it must be \(L\) (12th) or \(T\) (20th). Since \(T\) is already at 14, choose \(22\!\to\!L\). Between \(N\) (14th) and \(L\) (12th) lies only \(M\). Hence the required count is \(\boxed{1}\).
