Its 42 % But i like to solve in Easy way........
Let there are 100 houses
so number of items required = 300
number of item missing in whole village = 67+83+73=223
19 houses not have any 1 of these so
->100-19=81 houses should not have 2 or 3 item in there house
-> 223-19=204 item missing in this 81 house
let X number of house have 2 item missing so 81-X houses have 3 item missing
so-> 2X + 3(81-X)=204
X=39
81-x= 42 houses not have any of these item

From the given data, we know that there is shortage of atleast (67+83+73) 223 items in every 100 houses. Also, exactly 19 houses do not have just one item. It means that remaining 81 houses should account for the shortage of remaining (223-19) 204 items. If those remaining 81 houses do not have 2 items each, there would be a shortage of 162 items. But total of 204 items are short. Hence, atleast (204-162) 42 houses do not have all 3 items - tubelight, bulb and
