Understanding

Application

Fair calculation

CP of 1 fruit from 1st lot of fruits = 100/11

CP of 1 fruit from 2nd lot of fruits = 100/9

SP of 1 fruit = 100/10 = 10

Let total fruits bought = 99 x 2 = 198

Total CP of 1st lot of fruits = 99 x (100/11) = 900

Total CP of 2nd lot of fruits = 99 x (100/9) = 1100

 

Total CP = 900 + 1100 = 2000

Total SP = 198 x (100/10) = 1980

 

LCM of 9 and 11 = 99

 

Percentage loss = (2000 – 1980)/1980 = 1%

200/1980 = 0.01
