Question

Last weekend, a large number of drivers were random breath tested for drink driving. 1/3 of the drivers tested were women. Of the women who were tested, 5% were charged. If 25 women were charged, how many men were tested?

Answer 1

Let the total no.of peoples tested be x.

tested women=1×x/3=x/3

charged womens=5×(x/3)/100=5x/300=25

5x/300=25

5x=7500

x=1500

tested mens=1-(x/3)=(3x-x)/3=2x/3=2×500=1000.

Hope it helps you.
