In order to make the whole problem easier, you would have to get all the numbers to have the same denominator which would be 60.
1/10 * 6 = 6/60
1/4 * 15 = 15/60
1/5 * 12 = 12/60
2/15 * 4 = 8/60
Now that all the numbers have the same denominator, you would add them to get 41/60. 
In conclusion, the answer would be D.

The total number of people in the city surveyed by Annette= 480 people. 
Step-by-step explanation:
Let 'X' be the Total Number of people Annette surveyed.
Out of Total people in the city, only <u>180 people are not interested</u> in a new shopping mall.
Therefore, it is given in the question that <u>180 is 37.5% of Total number of people surveyed (X).</u>
step 1: 180= (37.5/100)*(X)
step 2: X= (180*100)/37.5
step 3: X= 18000/37.5
step 4: X= 480
