Question 110
Nitin was counting down from 32. Sumit was counting upwards, starting from 1, and he was calling out only the odd numbers. What common number would they call out at the same time if they were calling out at the same Speed?
Solution
Nithin is counting down from 32, and Sumit is counting up from 1, calling out odd numbers. Given that they call out at the same speed, let us have a column of numbers.
1 32
3 31
5 30
7 29
9 28
11 27
13 26
15 25
17 24
19 23
21 22
23 21
We see that they never call out the same number.
