olchik [2.2K]

The solution to the problem expressed  2358.

<h3>What is the meaning of significant figure?</h3>

Significant figure It is defined as the minimum number of digit us needed to express a number in scientific notation.

Therefore we get,

15.11+(142\times16.5)

First we have to multiply the given digits as per rule.

=15.11+2343

Now we will add both the digits, we get

=2358.11

As per given expression, we conclude that the number of significant figure is 4.

So, the answer will be, 2358.

Therefore, the correct option is, 2358.
