  • Let's denote the unknown percentage as "x."br /br /So, the equation becomes:br /x% of 280 + 18% of 550 = 143.8br /br /Now, calculate each part of the equation:br /x% of 280 = (x/100) * 280br /18% of 550 = (18/100) * 550br /br /Now, the equation becomes:br /(x/100) * 280 + (18/100) * 550 = 143.8br /br /Now, simplify the equation:br /(2.8x) + (99) = 143.8br /br /Subtract 99 from both sides of the equation:br /2.8x = 143.8 - 99 2.8x = 44.8br /br /Now, divide both sides by 2.8 to solve for x:br /x = 44.8 / 2.8 x = 16br /br /So, the value that should replace the question mark is 16.br /strongThe correct option is (d) 16./strong
