Answer 2

The required "option (D) 190"​ is correct.

Step-by-step explanation:

We have,

49.6 x 10.2 - 7.1 x 29.7 - 5.1 x 20.1

To find, the approximate result of the following  expression in whole numbers = ?

∴ 49.6 x 10.2 - 7.1 x 29.7 - 5.1 x 20.1

= 505.92 - 210.87 - 102.51

= 505.92 - 313.38

= 192.54

≈ 192

Hence, the required "option (D) 190"​ is correct.
