As the frequency is same so the itch is same for both the sounds.
As the loudness depends on the amplitude of the sound so the loudness of the second sound is more than the first sound.
The left end should the fulcrum be placed is 29.8 cm.
What is fulcrum?
The lever's pivot point is known as a fulcrum. You probably first came across a fulcrum on the playground, directly beneath the see-saw. Any general prop as well as support was referred to as a fulcrum in the 17th century. Thanks to physics class, it now has more scientific connotations.

Who is the father who arranges everyone's playdates? He serves as the focal point of the playground social group.
counter clockwise moments = clockwise moments
(0.055 kg * x) + (0.120*(x-25)) = 0.110 kg * (50-x)
0.055x + 0.12x - 3 = 5.5 - 0.11x
x = 29.8 cm
