Let's solve the expression step by step.

The expression is:

[
(4.67 - 23.5 \times (3.57 - 3.47)) : 0.4
]

Calculate the parentheses:
[
3.57 - 3.47 = 0.10
]

Multiply by 23.5:
[
23.5 \times 0.10 = 2.35
]

Subtract from 4.67:
[
4.67 - 2.35 = 2.32
]

Divide by 0.4:
[
2.32 : 0.4 = \frac{2.32}{0.4} = 5.8
]

So, the final result is:

[
\boxed{5.8}
]
