D. 6/10 ---> NOT equivalent to 8/12
Step-by-step explanation:
A. 2/3 ----> equivalent to 8/12
B. 24/36 ----> equivalent to 8/12
C. 4/10 ----> NOT equivalent to 8/12
D. 6/10 ---> NOT equivalent to 8/12
First add plus 5 to -5 and 22. Then -5 cancels outdo now u have 3b=27. Divide 3 to 3b and 27. Then you will have b=9
Lowest score earned to be qualified for an interview is 92.82
X : Marks scored in interview
X ~ N(80,100)
Here we need to find x such that P(X > x) = 0.10
using standard normal table,
we get P( z > 1.282) = 0.10
It's always easy to use Standard normal distribution to solve questions of normal distribution because standard normal is special case of normal distribution with mean 0 and standard deviation 1.
To convert x (which follows Normal distribution) to standard normal use: 
so, 
<em>hence,</em>
<em> </em>
Hence Lowest score earned to be qualified for an interview is 92.82
