PIT_PIT [208]

Answer:

23958, 23598, 25938, 25398, 29358, 29538....

Step-by-step explanation:

We have given the number cards for for 2 3 8 9 and 5. We have to find the different  ways Nia can arrange the cards to show only even numbers with the 2 in the ten thousands place.

The number should be even numbers with two in the ten-thousand places.

Only 8 is left as an even number. So 8 would be at the one's place.

In the ten-thousand places, arrange the three digits 3,9 and 5 in the middle.

So there are 3*2=6 ways to arrange the  middle three digits in the ten-thousand places.
