12 times breathe give 240 ml of pure $O_{2}$ . Each breathe gives 20 ml of $O_{2}$ .

Let us consider, volume of air per breathe= x ml.

Pure $O_{2}$ from inhaled air= $\frac{20}{100}x$ ml and Pure $O_{2}$ from exhaled air= $\frac{16}{100}x$ ml.

Pure $O_{2}$ from inhaled and exhaled air= 20 ml

So, $\frac{20}{100}x$ + $\frac{16}{100}x$ = 20

Therefore, x = 55.5 ml

So, volume of air per breath= 55.5 ml.
