Question

A shopkeeper purchase 12 ballons for rs10 and sells them at 10 ballons of rs 12.discuss the profit

Answer 1

C.P of 12 balloons=10,

C.P of 1 balloons =10/12=5/6=0.83,

S.P of 10 balloons =12,

S.P of 1 balloons=12/10=6/5=1.2,

then
profit =6/5 - 5/6 =(36-25)/30=11/30=0.36,

then
%profit=0.36/0.83×100
