To solve this problem, we can use basic principles of projectile motion and trigonometry. Let's break down the problem into smaller steps:

Step 1: Analyzing the problem
- The gun fires two bullets at angles of 60º and 30º horizontally.
- We need to determine the ratio of the maximum heights reached by the two bullets.

Step 2: Finding the initial velocities
- We know that the initial velocity of the bullets will have both horizontal and vertical components.
- The horizontal component remains the same for both bullets and is equal to the velocity of the bullets.
- Let's assume the initial velocity of the bullets is "v."
- The vertical component of the velocity for the 60º bullet is v * sin(60º) = v * √(3)/2.
- The vertical component of the velocity for the 30º bullet is v * sin(30º) = v * 1/2.

Step 3: Finding the time of flight
- The time of flight for a projectile can be determined using the formula T = 2 * (V0 * sin(θ)) / g, where V0 is the initial velocity, θ is the angle of projection, and g is the acceleration due to gravity.
- The time of flight for the 60º bullet is T1 = 2 * (v * √(3)/2) / g = √(3) * v / g.
- The time of flight for the 30º bullet is T2 = 2 * (v * 1/2) / g = v / g.

Step 4: Finding the maximum height
- The maximum height reached by a projectile can be determined using the formula H = (V0^2 * sin^2(θ)) / (2 * g), where V0 is the initial velocity, θ is the angle of projection, and g is the acceleration due to gravity.
- The maximum height reached by the 60º bullet is H1 = (v * √(3)/2)^2 / (2 * g) = 3v^2 / (8g).
- The maximum height reached by the 30º bullet is H2 = (v * 1/2)^2 / (2 * g) = v^2 / (8g).

Step 5: Finding the ratio of maximum heights
- The ratio of the maximum heights is H1 : H2 = (3v^2 / (8g)) : (v^2 / (8g)) = 3 : 1.

Therefore, the correct answer is option B) 3 : 1, as the ratio of the maximum heights reached by the two bullets is 3 : 1.
