A shopkeeper sells rice at cost price but uses a faulty weighing machine and thus gains a profit of 25%. Find how many grams rice he is giving in 1 kg ?
Answer & explanation
Correct answer: option 1
25% = \(\frac{1}{4}\)
If he uses faulty weight of 25% means he is making 25% profit for 1kg
So , 5x = 1000
4x = 800 grams ( used by shopkeeper)
