Best answer
Correct Answer - Option 2 : 255.5

Given:

15% of 570 + 25% of 680 = ?

Calculation:

Given expression is,

15% of 570 + 25% of 680

⇒ (15/100) × 570 + (25/100) × 680

⇒ (3/20) × 570 + (1/4) × 680

⇒ (3/2) × 57 + (680/4) 

⇒ (171/2) + 170

⇒ 85.5 + 170

⇒ 255.5

∴ The question mark '?' will be replaced by 255.5.
