Answer 1

price of 1st 3 lemon=5

so,price of 1 lemon=5÷3

2nd,price of 2lemon=4

price of 1 lemon=4÷2=2

again,price of 5 lemon=5÷3+2=11÷3

price of 1 lemon=11÷3÷5=11÷15

next,sells price of 5 lemon=9

s.p of 1 lemon=9÷5

there is gain.gain=9÷5-11÷15=16÷15

       gain percent=16÷15÷11÷3×100

                           =320÷11
