Answer 1

Answer:

119 is the number when divided (2 gives 1)(3 gives 2)...

Answer 2

Answer:

The answer is 119 .

Step-by-step explanation:

Let the required no. be 'a'

Now, follow the following steps to the answer:

1. since, everytime divided , a leaves remainder one less than divisor.
2. so, a = LCM(2, 3,4,5,6) -1
3. Here you'll get, 60-1 and 120-1
4. so, you have two options 59 and 119.
5. Now, check that which one of the above is divisible by 7 ( as a leaves nothing when divided by 7).
6. And there you get your answer i.e. 119.

Hope this helped you.
