Answer 1

Answer:

20%

Step-by-step explanation:

45% OF 180 + 35% OF 240 = 165

165/825= 0.2

0.2=20%

Answer 2

Answer :-

$( \frac{45}{100} \times 180) + ( \frac{35}{100} \times 240) = \frac{x}{100} \times 825 \\ 81 + 84 = \frac{x}{100} \times 825 \\ 165 = \frac{x}{100} \times 825 \\ \frac{165 \times 100}{825} = x \\ x = 20$
