A man buys a certain number of oranges at 20 for Rs.60 and an equal number at 30 for Rs.60. He mixes them and sells them at 25 for Rs.60. What Is gain or loss per cent
1). Gain of 4%
2). Loss of 4%
3). Neither gain nor loss
4). Loss of 5%

This Question has 3 answers.

Loss of 4% seems correct.

Let the man buy 60 oranges (LCM of 20 and 30) of each kind.

CP of the 60 oranges of the first kind=6020×60=120Rs.

Total CP of 120oranges =(180+120)Rs.=300

Their SP=6025×120=288 Rs.

Loss=(300288)=12 Rs.

Loss percent= 12300×100=4
