How many 7-digit numbers exist which are divisible by 9 and whose last but one digit is 5?
@Estallar12 said:How many 7-digit numbers exist which are divisible by 9 and whose last but one digit is 5?
900000.such numbers ..out of this every 9th number will be divisible by 9 so
900000/9=100000
@lopagargg said:900000.such numbers ..out of this every 9th number will be divisible by 9 so900000/9=100000
but what about the last but one digit as 5??
@manoj_msr said:but what about the last but one digit as 5??
Yeah. That is 90000 total such numbers.
See, fix 10s digit as 5. Now, first place 9 ways and rest all 5 places 10 ways => 9*10^5 = 900000 ways,
Now, 1/9 will be divisible by 9. :)
