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?​

Answer 1

Answer:

Cost Price of 1- lemon=Rs. 3/4= Rs. 0.75

Sale Price of 1- lemon= Rs 4/5 = Rs. 0.80

So gain %= (0.80–0.75)/0.75 x 100

= 5/75 x100= 20/3 %

Gain percentage = 6⅔%

or

4c.p = 3

For one lemon c.p=3/4

Similarly for s.p=4/5

So c.p of 20 = 20×3/4 = 15 rs

And s.p of 20 = 20×4/5 = 16rs

So profit = 16-15 = 1rp

Profit % = 1/ 15 ×100 = 6.66
