Correct Answer :

Option D

2

Solution :

To find the approximate value that should come in place of the question mark (?), let us write down the given equation:

539 15 × 383 48 = ? × 12 2

Since we need an approximate value, we can round the numbers to their nearest easily divisible values to simplify the calculation:
- 539 is very close to 540, and 540 is perfectly divisible by 15:
539 15 540 15 = 36
- 383 is very close to 384, and 384 is perfectly divisible by 48 (since 48×8=384):
383 48 384 48 = 8

Now, let us substitute these approximate values back into the left-hand side of our equation:
36 × 8 = 288

On the right-hand side of the equation, we have:
? × 12 2 = ? × 140 4

Now, equate the simplified left-hand side to the right-hand side:
288 = ? × 144

Solving for ?:
? = 288 144 = 2

Thus, the approximate value that should come in place of the question mark is 2.
