Question
A dishonest dealer professes to sell his goods at cost price. But he uses a false weight and thus gains 6 ¹⁸/ ₄₇ % . For a kg, he uses a weight of?
Options
A. 953 gms
B. 940 gms
C. 960 gms
D. 947 gms

Correct Answer

940 gms

Explanation

Let the error be W gms.
Then, [W/ (1000 - W)] x 100 = 300 / 47
? W / (1000 - W) = 3 / 47
47 x W = 3000 - 3 x W
? W = 60

So, he uses a weight = (1000 - 60)gm = 940 gms for 1 kg.
