A shopkeeper bought 30 kg of wheat at the rate of Rs. 45 per kg. He sold 40% of the total quantity at the rate of Rs. 50 per kg. Approximately, at what price per kg should he sell the remaining quantity to make 25% overall profit ?
Correct Answer: Description for Correct answer:
Total cost of wheat =30 x 45 = Rs.1,350/-
Price of 40% of the wheat = 30 x \( \Large \frac{40}{100} \) x 50
= Rs.600/-
Remaining wheat = 30 - 12 = 18 kg
Therefore Required price = \( \Large \frac{1350 x 125/100 - 600}{18} \)
= \( \Large \frac{1687.5 - 600}{18} \) = Rs. 60/-
