Question

man bought apples at 10 for 25rs and sold them at 25 rs per dozen find his gain or lose percent​

Answer 1

Answer:

Step-by-step explanation:

Question is from aptiude or olympiad.

We will firstly take LCM of 10apples and a dozen means 12apples which is

60

cp of 10 apples = 25rs

then cp of 60 apples = 25 * 6 = 150rs

Now

sp of 12 apples is = 25 rs

then sp of of 60 apples is = 25 * 5 = 125 rs

We can clearly see that man made a loss of 25rs

L% = (L/cp) * 100

L% = (25/150) * 100

     =(1/6) * 100

     =100/6

     =16.67% = 16$\frac{2}{3}$ %
