If the positions corresponding to the multiples of 5 in English alphabet are replaced by symbols and that of multiples of 7 by digits, how many letters will be left? Correct Answer 18
Multiples of 5: 5, 10, 15, 20 and 25
Multiples of 7: 7, 14, 21
So, 5th, 10th, 15th, 20th and 25th letters in alphabet are replaced by symbols
7th, 14th and 21st letters will be replaced by digits
English alphabet series:
[ alt="SBI clerk 1" src="//storage.googleapis.com/tb-img/production/18/01/SBI%20clerk_1.PNG" style="height:103px; width:609px">
After replacing, the new series will be:
[ alt="SBI clerk 2" src="//storage.googleapis.com/tb-img/production/18/01/SBI%20clerk_2.PNG" style="height:105px; width:605px">
Therefore, no. of letters left = 18
