Question

sameer bought 1600bananas at Rs.24 adozen he sold 900 bananas of them at 2 for Rs5 and remaining at 5 for Rs 15 find his gain or loss percent.

Answer 1

cp = (1600×24)/12=3200

sp= (900×5)/2 + (700×15)/5
sp= 2250+2100=4350

so it's profit = sp- cp = 4350-3200=1150

so profit percent = (profit /cp)×100

P%= (1150/3200)×100

=1150/32=575/16=35.9375=35.94%

Answer 2

cp of 12 bananas = Rs,24

so cp of 1600 bananas = Rs,3200

now sp of 1600 bananas = [900*5/2]+[77*15/5]

                                           =Rs.4350

gain = 4350-3200 = Rs.1150

gain percent = [gain/cp]*100

= [1150/3200]*100

= 34.6%
