Question

A girl buys lemons at 4 for rs 3 and sells them at 5 for rs 4 How much did she gain or loss if she sell 20

Answer 1

Answer:

C.p. of lemons = tot. amt./no. of lemons

c.p. = rs 3/4 = rs0.75

total amt spent on 20 lemsons = 0.75*20 =rs 15

Similarly s.p. of lemons = 4/5 = rs0.80

total amt gained on 20 lemons =0.8*20= rs16

Gain = s.p -c.p = 16 - 15 =rs 1
