Answer 1

Answer of this question is 240

Answer 2

The number of crimes involving drugs is 240, that is option c is correct.

Step-by-step explanation:

According to the given information, there were 720 crimes committed in the ninth precinct. Now, given that the ratio 4:2:3 represents in the crimes involved theft, rape, and drugs.

Now, let 4x be the number of crimes involving acts of theft.

Also, let 2x be the number of crimes involving acts of rape.

Also, let 3x be the number of crimes involving acts of drugs.

Then, the total number of crimes committed in the ninth precinct is equal to (4x + 2x + 3x) number of crimes.

This means that the total number of crimes committed in the ninth precinct is equal to 9x number of crimes.

According to the given information,

9x = 720.

Or, x = $\frac{720}{9}$

Or, x = 80.

Then, the number of crimes involving acts of theft = (4*80) = 320.

Again,  the number of crimes involving acts of rape = (2*80) = 160.

Again,  the number of crimes involving acts of drugs = (3*80) = 240.

Thus, the number of crimes involving drugs is 240, that is option c is correct.
