Answer:

Option D.

Explanation:

Juanito estimated that 31% of 517 is 204 is estimated wrong because

31% of 517 = 0.31 × 517 = 160.27

Now we will go through all the options.

A. 30% of 520 = 0.30 × 520 = 156

B. 40% of 520 = 0.40 × 520 = 208

C. 30% of 510 = 0.30 × 510 = 153

D. 40% of 510 = 0.40 × 510 = 204

Option D.
