Question

girl buys lemon at 4 for 3 rupees and sells them at 5 for 4 rupees how much percent gain or less does she make

Answer 1

Answer:

cost of 4 lemon = 3:

cp of 1 lemon = 3/4

sp of 5 lemon = 4

sp of 1 lemon = 4/5

profit= sp_cp= 4/5_3/4 =1/20

profit%= profit/cp×100

1/20/3/4×100 =20/3 %

Answer 2

Step-by-step explanation:

c.p of 4 lemons=3

c.p of 1 lemon=3/4

s.p of 5 lemons =4

s.p of 1 lemon=4/5

gain=s.p-c.p

gain=4/5-3/4

gain=1/20

gain%=(gain/c.p)×100

=((1/20)/(3/4))×100

=(1/20)×(4/3)×100

=6.67%
