3% of 800 = 24

so , 24 women are wearing 1 earring each.. this means you have24earrings so far..

now the remaining number of women is: 800-24 =776

out of these 776, half of them (388) are wearing 2 earrings each.. that means you have [388*2] earrings..

and the remaining half of 776, that is 388, are wearing no earrings...that is you have no earrings in this case...

so what is the total number of earrings??
