What is the faulty weight used by a dishonest shopkeeper instead of the original weight of 1 kg to get a profit of 25%?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 800 grams
Let the faulty weight be x grams
Given that
Original weight is 1000 grams
The profit % = 25%
Formula used
Profit% = [(Original weight - faulty weight)/faulty weight] × 100
According to the question
⇒ 25 = [(1000 - x)/x] × 100
⇒ 0.25 = (1000/x) - 1
⇒ 1000/x = 1.25
⇒ x = 1000/1.25 = 800 grams
