If you use a certain formula on 13, you end up with 7.

Under the same formula, 2352 becomes 16, 246 becomes 14, 700 turns into 16, and 1030 becomes 14.

What would 9304 become?

Here is the answer for your question....

Convert the number into binary. Count the number of zeros and number of ones.
Next number of zeros multiple by one and number of one multiple by two and then add these two results...

13 = 1101 = 1(no of zero)*1 + 3(no of one)*2 = 1+6 = 7

246 = 11110110 = 2*1+6*2 = 14
