Annual Income = I

2% of annual income = 2I/100

average 100 units of currency and 1% of I = [100 + I/100]/ 2


Question stem:

2I/100 + [100 + I/100]/ 2


2I/100 + (10000 + I)/200

(4I + 10000 + I)200

5I/200 + 10000/200

I/40 + 50

Hence C.

Hope this helps.

Same as morgoth ! just that i plug in values always ...

Let the Income earned is 1000$

2 percent of income is 20

and the average of of 100 units and 1 percent of income

(100+10)/2=55
so total 75

plugin in back ! only C satusfies
