Answer 2

Answer:

Step-by-step explanation:

Profit % = error term / actual weight *100

Here, it's given that the shopkeeper is incurring loss. So, Profit percentage is (-20)%

Now, using this formula, we have,

-20 = x/(1000-x)*100

-20/100= x/(1000-x)

Solve this equation to get x as -250

That means actual weight that he was balancing on a 1kg balance was [1000-(-250)] which is equals to 1250gms.

Note:- Don't assume that the shopkeeper is always dishonest and making profits. Here, it's specifically given that he loses 20% ( take -20), so obviously, he would have been balancing more than 1 kg, that's why he is in loss. So, options that are less than 1000 gms will automatically gets eliminated.

A shopkeeper can be naive too
