SUBHASH TULSYAN 10 years ago

bro i think the last term of the question is incorrect
i hv explained it as follows:
9=(9*2^0)+(2^1-(2+0))
19=(9*2^1)+(2^2-(2+1))
40=(9*2^2)+(2^3-(2+2))
83=(9*2^3)+(2^4-(2+3)) & so on
so its n term will be
n=(9*2^(n-1))+(2^n-(2+(n-1)))

How many positive integers less than 10,000 are there in which the sum of the digits equals 5?

Reply Like? Yes | No

Anand Dwivedi 11 years ago

I believe the answer to be C: 56.

Basically, the question asks how many 4 digit numbers (including those in the form 0XXX, 00XX, and 000X) have digits which add up to 5. Think about the question this way: we know that there is a total of 5 to be spread among the 4 digits, we just have to determine the number of ways it can be spread.

Let X represent a sum of 1, and | represent a seperator between two digits. As a result, we will have 5 X's (digits add up to the 5), and 3 |'s (3 digit seperators).

So, for example:

XX|X|X|X = 2111
||XXX|XX = 0032

etc.

There are 8C3 ways to determine where to place the separators. Hence, the answer is 8C3 = 56.
