wrong option (Question:315719.0)

wrong option is selected as answer

Question:

A dishonest dealer sells his goods at the cost price and stills earns a profit of 35% by underweighting. What does he use for 2 kg?

Options:

1400 grams

1420 grams

1600 grams

1481.50 grams

Solution:

Gain% = $(\frac{E r r o r}{T r u e w e i g h t - E r r o r} \times 100)$

$∴$ 35= $\frac{x}{1000 - x} \times 100$

$∴$ 35000 – 35x=100x

$∴$ 35000 = 135 x

$∴$ x= $\frac{35000}{135}$ $\approx 259.25$

Thus , he uses 1000 - 259.25 = 740.75 grams

$∴$ He uses 1481.50 kg for 2 kg weight
