Option B:

Solution:
Given sound level = 120 decibel
To find the intensity of a fire alarm:

where 
Step 1: First divide the decibel level by 10.
120 ÷ 10 = 12
Step 2: Use that value in the exponent of the ratio with base 10.

Step 3: Use that power of twelve to find the intensity in Watts per square meter.


Now, do the cross multiplication,




Option B is the correct answer.
Hence
.
SOLUTION:
= ( 7 / 8 )m + 9 / 10 - 2m - 3 / 5
= - ( 9 / 8 )m + 3 / 10
The answer is C.
Hope this helps
