1. Find the 5-digit number by using the clues below. Also write its number
name in Indian system.
a) 2 is at ones place b) 1 is at hundreds place c) 5 is not next to 1
or 2
d) 4 is next to 5
e) Digits used are 1,2,3,4 and 5.​

Answer 1

Answer:

54,132

Step-by-step explanation:

Let the number be a b c d e

Using conditions a and b: a b 1 d 2

If 5 is not after 1, it could occupy either thousands or ten thousands place

If 4 is after 5, then this eliminates the possibility of 5 being in the thousands place, as 1 is already occupying the space next to 5.

So the number would be: 5 4 1 d 2

Finally since the digits used are 1,2,3,4,5, the final number would be 54,132
