By selling 3 dozen oranges for ₹405, a trader loses 25%. How many oranges should he sell for ₹288 if he needs to earn a profit of 20% in the transaction?
Answer & explanation
Correct answer: option 3
N1 = 36
P1 = 75
Rs1 = 405
N2 = ?
P2 = 120
Rs2 = 288
Formula = \(\frac{N1 × P1}{Rs1}\) = \(\frac{N2 × P2}{Rs2}\)
Formula = \(\frac{36 × 75}{405}\) = \(\frac{N2 × 120}{288}\)
No. of oranges required (N2) = 16
