1.	If a code involves one letter of English alphabet at first place and a number at second place. Numbers can be used from 1 to 9. How many codes are possible using the letters of alphabet and numbers?(a) 234(b) 260(c) 314(d) 324I have been asked this question during an internship interview.My question is from Fundamental Principle of Counting topic in division Permutations and Combinations of Mathematics – Class 11
Answer» The correct answer is (a) 234 Easiest explanation: Since there are 26 LETTERS in English ALPHABET and 9 possible DIGITS from 1 to 9. So, by the fundamental principle of counting, total possible codes are 26*9 = 234.
