What approximate value will come in place of question mark (?) in the following question? (You are not expected to calculate the exact value)

$\frac{1}{4}$ of 33 + 98% of 15.02 - 3.91 of 2 = ?

The correct answer is 15.

We need to find the approximate value of the question mark (?) in the following expression:

$\frac{1}{4}$ of 33 + 98% of 15.02 - 3.91 of 2 = ?

Let us simplify each term by approximating to the nearest convenient numbers:

Step 1: Approximate the first term, $\frac{1}{4}$ of 33.

Since 33 is close to 32 (which is divisible by 4):

$\frac{1}{4}\times 33=8.25\approx 8$

Step 2: Approximate the second term, 98% of 15.02.

Here, 98% is approximately 100% and 15.02 is approximately 15:

$98\%\text{ of }15.02\approx 100\%\text{ of }15=15$

Step 3: Approximate the third term, 3.91 of 2.

Since 3.91 is approximately equal to 4:

$3.91\times 2\approx 4\times 2=8$

Step 4: Substitute these values back into the main expression:

$?\approx 8+15-8$

$?\approx 15$

Hence, the approximate value that comes in place of the question mark (?) is 15.
