Question
A retailer purchased 50 kg of a vegetable from a
wholesale market. He sold half of it at a profit of ₹450, and the rest at a loss of ₹275. What was the difference (increase ₹) between the two selling prices per kg of the vegetable?Solution
Let CP of 1 kg vegetable be Rs. x Total CP = 50x Now, SP of 1st half = 25x + 450 SP of 2nd half = 25x - 275 Difference in SP = (25x + 450)/25 - (25x - 275)/25 ⇒ (25x + 450 - 25x + 275)/25 ⇒ 725/25 ⇒ 29
