How many speakers of the seven most widely spoken languages are there, spoken as either a first or a second language?

A5.223 billion
B5.116 billion
C5.156 billion ✓ Correct
D5.215 billion
Correct answer: (C) 5.156 billion
Explanation

The total is 5.156 billion, so the answer is 5.156 billion.

Adding the first-language speakers gives 1386 plus 1000 plus 280 plus 270 plus 220 plus 160 plus 140.

That total is 3456 million, which is 3.456 billion.

A further 1.7 billion speak one of these languages as a second language.

So the grand total is 3.456 billion plus 1.7 billion.

That is 5.156 billion.

So the answer is 5.156 billion.
