To solve this inequality, we can break it down into two separate inequalities:

1) 121/27.54/11 < n
2) n < 100/21:25/126

Let's solve each inequality separately:

1) 121/27.54/11 < n

To simplify the left side of the inequality, we can divide 121 by 27.54 and then divide the result by 11:

121 ÷ 27.54 ÷ 11 ≈ 0.404

So the first inequality becomes:

0.404 < n

2) n < 100/21:25/126

To simplify the right side of the inequality, we can divide 100 by 21.25 and then divide the result by 126:

100 ÷ 21.25 ÷ 126 ≈ 0.037

So the second inequality becomes:

n < 0.037

Therefore, the solution to the original inequality is:

0.404 < n < 0.037
