shortcut (Question: 233009.0 )

let sp=100 each ie 200
cp1=100*5/4
cp2=100*5/6
total cp=100(50/24)
profit=200/24
now 200 =9.5 lakh
200/24 will be 9.5/24
ie only 1 calculation in the end

Dear Student
It's a special case when the values of both profit and loss are similar, there will be net loss

Formula of the loss percent=(x)^2/100=400/100=4
Thus loss percent=4%
Total SP =96%CP
their is a clear indication of 4% loss from the above equation
9lakh=96%CP

Or the loss % value=9*4/(96)
loss of rs 37500
You can also solve the above question easily by the shortcut method you gave
