A dishonest dealer professes to sell grains at cost price, but he uses a weight of 925 g for 1 kg weight. Find his gain percentage. (Approximate to two decimals.)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 0.0811.
The dealer gives only 925 g instead of 1000 g but charges for 1 kg.
Gain = (1000 - 925) / 925 × 100 = 75 / 925 × 100 ≈ 8.11% = 0.0811
