Answer: According to some scientific estimates, there were about 100 million people in the world during the exodus from Egypt. Jews comprised 3% of the population, which means that now there should be 6.9 billion x 3% = 200 million. The number of Jews in the world, left of the two tribes is 14 million. One tribe is 7 million. As of today, all the tribes amount to 7 million x 12 tribes = 84 million.
Many were killed during the persecution of the Jews in the Middle Ages. But let’s take only the 6 million who where murdered in the Holocaust. Since 1940 the world population has grown three times, and so 6 million x 3 = 18 million. This means that there could have been 18 +14 = 32 million Jews, together with those murdered in the Holocaust. And one tribe is 16 million.
16 million x 12 = 192 million Jews in 12 tribes as of today. This means that the number of Jews is about 200 million: 3% of the world’s population.
