Question

How many numbers greater than a billion but less than 10 10 can be formed such that the sum of the digits is equal to 3?

Answer 1

Answer:

The answer is zero as no numbers can be formed which follow all the given conditions.

Step-by-step explanation:

We know that: 1 billion > 1010

Thus, if we assume a required number, 'x',

According to question: x < 1010

and also: x > 1,000,000,000

but we know that: 1,000,000,000 > 1010

So, we can say:

x > 1010

Thus, it leads to a contradiction as x can either be greater than or less than 1010 and not be both at a time. Thus, our assumption is wrong and the required number does not exist.
