What approximate value should come in place of the question mark (?) in the following equation?

$179.98\%\text{of}24.99+155.89÷\sqrt{143.98}+?=229.98$

The correct answer is 188.

To find the approximate value of the question mark (?), we approximate each term in the given equation to its nearest integer value:

$179.98\%\approx 180\%$

$24.99\approx 25$

$155.89\approx 156$

$\sqrt{143.98}\approx \sqrt{144}=12$

$229.98\approx 230$

Now, substitute these simplified values back into the original equation:

$(180\%\text{of}25)+(156÷12)+?=230$

Step 1: Calculate 180% of 25:

$180\%\text{of}25=\frac{180}{100}\times 25=45$

Step 2: Calculate the division part:

$156÷12=13$

Step 3: Combine the numerical terms and solve for the unknown value (?):

$42+?=230$

$?=230-42$

$?=188$

Therefore, the approximate value that should come in place of the question mark (?) is 188.
