Why do the Indian telecom operators offer their services with 28 days validity, not 30 days?😡😡

Here telecom operator are very clever, b ecause telecom operators want to earn money of 13 months instead of 12 months. Let do the calculation and find out why telecom operators are offering 28 days validity. Each month they get 2 days more, therefore in a year they get additional 24 days. There are 7 month which has 31 days so they get additional 7 days.Now in case of February ,it has only 28 days not 30. So the total number of days they get are=24+7-2=29 days. So if you recharge 12 times then more 29 days are left in a year.🤔🤔 Means for another 29 days you have to recharge from that telecom operator.😫😫 So you have to recharge 13 times in a year instead of 12 times in a year. So telecom operators provide 28 days validity only. First one telecom operator started and then another telecom operators also understood this concept and they also applied 28 days validity both in data packs and voice packs.😱😱😱

1/ The speed of light is generally rounded down to 186,000 miles per second. In exact terms it is 299,792,458 m/s (metres per second - that is equal to 186,287.49 miles per second). 2/ It takes 8 minutes 17 seconds for light to travel from the Sun's surface to the Earth. 3/ October 12th, 1999 was declared \\"The Day of Six Billion\\" based on United Nations projections. 4/ 10 percent of all human beings ever born are alive at this very moment. 5/ The Earth spins at 1,000 mph but it travels through space at an incredible 67,000 mph. 6/ Every year over one million earthquakes shake the Earth. 7/ When Krakatoa erupted in 1883, its force was so great it could be heard 4,800 kilometres away in Australia. 8/ The largest ever hailstone weighed over 1kg and fell in Bangladesh in 1986. 9/ Every second around 100 lightning bolts strike the Earth. 10/ Every year lightning kills 1000 people. 11/ In October 1999 an Iceberg the size of London broke free...

A brief history of the Morse code

££) In the early nineteenth century, all of the essential components necessary to construct an electrical communication system had been discovered. The most important of these were the battery by Volta, the relationship between electric current and magnetism by Oersted, and the electromagnet by Henry. It now remained for someone to find a practical method to combine these technologies into a working communication system. ££)Some commercial electrical communications systems existed in Europe as early as the 1830s. A classic example of this is the English ‘Needle Telegraph’. The needle telegraph required two or more lines to form a complete circuit. It was relatively slow and the design of the transmitting and receiving instruments was complex. Something simple and efficient was needed. ££)The Morse system of telegraphy was invented by Samuel Finley Breese Morse (an American painter and founder of the National Academy of Design in New York) in the 1840s ...
