A seller bought x kg of apple for Rs.2000 and also bought (x + 5) kg of oranges for Rs.1800 and the seller sold each kg of apple and orange at a profit of 40% and 25% and the selling price of each kg of orange is Rs.150. Find selling price of (x – 5) kg of apple.
a) Rs.1800
b) Rs.1400
c) Rs.2500
d) Rs.2000
e) None of these
Sol:
Cost price of each kg of apple = 2000/x
Cost price of each kg of orange = 1800/(x + 5)
1800/(x + 5) * 125/100 = 150
1800/(x + 5) * 5/4 = 150
x + 5 = 15
x = 10
Cost price of each kg of apple = 2000/10 =
Rs.200
Required selling price = (10 – 5) * 200 * 140/100
= 5 * 200 * 7/5 = Rs.1400
