The correct Answer is:
C
Number of letter.s places replaced by symbols in the English alphabet
= Multiples of 5 = 5th, 10th, 15th, 20th, 25th (5 places).
Number of letter.s places replaced by digits = Multiples of 7 = 7th, 14th, 21st (3 places)
So, Total number of letters replaced = 5 + 3 = 8.
So, Number of letters left = (26-8)= 18.
