Solution:


The given expression is:

540 - 36 12 75 x 55

We need to replace each symbol with its corresponding operation as given:

= 540 - 36 + 12 ÷ 75 x 55
= 540 - 36 + (12 ÷ 75) x 55 (Division has higher priority than multiplication)
= 540 - 36 + 0.16 x 55
= 540 - 36 + 8.8
= 512.8

Hence, the value of the expression is 512.8.

Therefore, the correct option is (e) None of these.
