These questions are based on the five three digit numbers given below :
346 815 428 271 732
Series : 346 815 428 271 732
If ‘1’ is added to the first digit of every number and ‘1’ is subtracted from the third digit of every number, new numbers
346 -> 445 = $5-4=1$
815 -> 914 = $9-4=5$
428 -> 527 = $7-5=2$
271 -> 370 = $3-0=3$
732 -> 831 = $8-1=7$ (difference more than 5)
=> Ans - (E)
