Can you please post any explanation given to show how the answer is 'C' -
50 + I/40 ?

Language is little complex, what sentence means is to take the average of
100 and 1% of Income
Av of 100+1%of I
=(100+0.01)/2
=50+0.01/2
=50+1/200
Add 2% of I to above equation = 2*I/100+I/200+50
(2*I/100 divide and multiply this equation by by 2)
=2*2*1/200+I/200+50
= 5*I/200+50
=I/40+50
hope its clear now, let me know if you need more explanation.

Yikes, the notorious GMAT deceptive wording...huh...

Thanks Amitabh. That's a clear explanation.

nice prasad
OA is C

lets make life EASY

So we make $ 100

My tax is: 2 + 101/2

105/2 or 50 +5/2

Only C gives us 2/5 when you have I=100

That's it.

i couldnt get this part.
I also started by takin I =100 ,but couldnt do the 101/2 par..but how u arrived

105/2 = 50+2/5

2% of I+ AVG of {100 and 1% of I}
=> 2I/100 + {100+(I/100)}/2
=>I/50 + 50 + I/200
=> 50+ 5I/200
=> 50 + I/40 ------------- Answer "C" --------

I edited it is 5/2! duh!

101/2 part is the average of 100 CURRENCY ( which is 1 dolar! ) and 1% of of the salary = 1 dolar

so ($100 + $1) / 2
