Question

If the number of police officers (a) is 4 less than 3 times the number of traffic control stations (d), then how many police officers will be there for 50 control stations?

• A. 146

Answer 1

The correct option is A 146
It is given that the number of police officers (a) is 4 less than 3 times the number of traffic control stations (d).

So, the relationship can be expressed as: $a=3d-4$

Now, the value of d (no. of traffic control stations) = 50
Putting this value, we get:
$a=3\times 50-4$
$a=146$

∴ Number of police officers = 146
