A seller professes to sell his grapes at cost but still gains (100/9)% by using faulty weight . What weight does he use instead of 1 kg?
Show answer & explanation
Correct answer: B
Explanation
The Correct answer is option 2 i.e. 990 g
Given that
A seller professes to sell his grapes at cost but still gains (100/9)% by using faulty weight
Gain = 100/9 % = (100/9)/100 = 1/9
Ratio of C.P. and S.P. = 9 : 10
Let C.P. of 1000 gram grapes = Rs. 1000
According to the question
Faulty weight/1000 = 9/10
Faulty weight = (9/10) × 1000 = 900 grams
