First he sold 50%
So 10kg.
CP of 10 kg=40×10=400
SP of 10 kg=(40+40×25/100)×10=50×10=500
Then he sold 25%
So 5kg.
CP of 5 kg=40×5=200
SP of 5 kg=(40+40×5/100)×5=42×5=210
Then he sold remaining.
So 5kg.
CP of 5kg=200
SP of 5kg=(40-40×15/100)×5=34×5=170
Total CP=800
Total SP=880
As SP>CP so,its profit.
Profit =80
Profit %=80/800×100=10%
So 10kg.
CP of 10 kg=40×10=400
SP of 10 kg=(40+40×25/100)×10=50×10=500
Then he sold 25%
So 5kg.
CP of 5 kg=40×5=200
