In a certain code, 15789 is written as X T Z A L and 2346 is written as N P S U. How is 23549 written in that code?

N P T S L

Respective code has been given to a corresponding letter. The codes are as follows:

1 = X, 5 = T, 7 = Z, 8 = A, 9 = L and 2 = N, 3 = P, 4 = S, 6 = U. Thus, from these codes we can get the answer i.e.

2 = N, 3 = P, 5 = T, 4 = S, 9 = L
