In a certain village live 800 women. Three percent of them are wearing one earring. Of the other 97 percent, half are wearing two earrings and half are wearing none. What is the total number of earrings being worn by the women?
3% of 800 = 24
so , 24 women are wearing 1 earring each.. this means you have 24 earrings 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??
