    83313833\frac{1}{3} g

  4. D.

    850 g

Answer

C

Explanation

Let xx be the false weight used for 1000 g. Gain%=1000−xx×100\text{Gain\%} = \frac{1000 - x}{x} \times 100 20=1000−xx×100  ⟹  0.20x=1000−x  ⟹  1.2x=100020 = \frac{1000 - x}{x} \times 100 \implies 0.20 x = 1000 - x \implies 1.2 x = 1000 x=833.33 g=83313 g.x = 833.33\text{ g} = 833\frac{1}{3}\text{ g.}
