Question

Babu is a fruitseller, hi bought 100 kg orange at ₹42 per kg. 20% of them are rotten and remaining orange sold at ₹ 54 per kg. find his gain or loss percentage on this transaction​

Answer 1

Total Oranges=100kg

Rotten Oranges=20kg

Remaining Oranges=80kg

Cost Price =100×42

=4200 Rs

Sell Price=80×54

=4320 Rs

Gain= 4320-4200

=120 Rs

Gain % = (120/4200)×100

=120/42

=20/7 or 2.857%

Answer 2

Answer:

C.P. of one kg of orange = ₹42/kg

C.P. of 100 kg of oranges = ₹4200

GIVEN THAT,

20% of them are rotten.

Rotten oranges = 20/100×100= 20 kg

Remaining oranges = 100- 20= 80 kg

S.P. of remaining oranges =₹54×80

=₹4320

4320 > 4200

S.P. > C.P.

SO, THERE IS A GAIN.

GAIN = 4320 - 4200 = 120

GAIN% = GAIN/CP×100

GAIN% = 120/4200×100

GAIN% = 20/7=2.857%
