What percentage of houses do not have tubelight, bulb and
Answer / guest
42% houses do not have tubelight, bulb and fan.
Let's assume that there are 100 houses. Hence, there should
be total 300 items i.e. 100 tubelights, 100 bulbs and 100
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 fan.
Thus, 42% houses do not have tubelight, bulb and fan.

Ali Baba had four sons, to whom he bequeathed his 39 camels, with the proviso that the legacy be divided in the following way : The oldest son was to receive one half the property, the next a quarter, the third an eighth and the youngest one tenth. The four brothers were at a loss as how to divide the inheritance among themselves without cutting up a camel, until a stranger appeared upon the scene. Dismounting from his camel, he asked if he might help, for he knew just what to do. The brothers gratefully accepted his offer. Adding his own camel to Ali Baba's 39, he divided the 40 as per the will. The oldest son received 20, the next 10, the third 5 and the youngest 4. One camel remained : this was his, which he mounted and rode away. Scratching their heads in amazement, they started calculating. The oldest thought : is not 20 greater than the half of 39? Someone must have received less than his proper share ! But each brother discovered that he had received more than his due. How is it possible?
