Answer:
here is your answer... hope u get it
Step-by-step explanation:
cp of 1 electric bulb =rs.40
total bulbs =1000
cp of total bulbs = rs. 40000
broken bulbs=100
remaining bulbs = 900
sp of 1 bulb = rs.45
sp of total bulbs = 45*900
=rs. 40500
profit %=(sp -cp)/cp*100%
=(40500-40000)/40000*100%
=500/400%
=1.25%
