Question

a fruit vendor buys oranges at 6 for rs 10 and an equal number at 10 for rs 20. he mixes them and sells at Rs 21.60 per dozen. find his gain or loss percent.

Answer 1

NO OF ORANGES HE BOUGHT =6+10=16
TOTAL COST=10+20=RS.30
C.P OF EACH ORANGES IS 30/16
NOW HE SELLS IT AT RS.21.6 FOR 12
S.P OF ORANGES=21.6/12
SINCE 30/16 IS GRATER THAT 21.6/12
HE HAD A LOSS
THE LOSS =30/16-21.6/12=RS 3.6
I HOPE THIS HELPS U....

Answer 2

loss percent equals to 3.6÷23.52×100
                                    3600÷23520×100
                                    36000÷2352
                                    15.30 percent
