Some fruits are bought at 15 for ₹140 and an equal number of fruits at 10 for ₹120. If all the fruits are sold at ₹132 per dozen, then what is the profit percent in the entire transaction?
Answer & explanation
Correct answer: option 1
Let total fruit brought = 30
So, Let 30 fruits are bought at 15 for Rs. 140,
then cost of 30 fruits = \(\frac{140}{15}\) × 30 = Rs. 280
⇒ 30 fruits are also brought at 10 for Rs. 120, then cost of 30 fruits = \(\frac{120}{10}\) × 30 = Rs. 360
⇒ Total cost of 60 fruits = Rs. 280 + Rs. 360 = Rs. 640
SP of 12 fruits = Rs. 132
SP of 1 fruit = Rs. 11
SP of 60 fruits = Rs. 11 × 60 = Rs. 660
Profit = 660 – 640 = Rs. 20
Profit percent = \(\frac{20}{640}\) × 100 = 3.125
