A digital camera salesman earns a commision of $12 per camera for the first 10 cameras he sells each day. If the salesman earns a commision of $16 a camera for each one sold over 10, how many cameras did he sell today?
(1) Yesterday the camera salesman sold 10 cameras.
(2) The salesman earned $48 in commision more today than yesterday.

statement 1 gives us no information about today, so we cannot determine how many cameras he sold today. So alone is insufficient.
In Statement 2 , we do not know the number of cameras sold or commision earned yesterday. So , alone insufficient.
If we combine 1 and 2 together, we have number of cameras sold yesterday and Commission earned today more than yesterday which will give value of total number of cameras sold today.
Hence , option C (both statements together)

Let N be the total number of cameras sold by the salesman TODAY.
First 10 cameras, the salesman earns a commission of $12 per camera.
For every additional camera sold, the salesman earns a commission of $16 per camera.
WE NEED TO FIND: N
Statement 1:
(1) Yesterday the camera salesman sold 10 cameras.
This is about yesterday’s sales. We need data to ascertain today sales.
Hence, Insufficient
Statement 2:
(2) The salesman earned $48 in commision more today than yesterday.
We can conclude, the sales was more than 10.
Secondly, the difference in sales from today than yesterday was $48 = 3 more.
Since, we don’t know the exact quantity of quantities sold yesterday.
Hence, Insufficient.
Combining both statements 1 and 2, we get
Commission earned Yesterday = 10*12 = $120 (as 10 cameras were sold).
Commission earned today = $48 extra = $120+$48 = $168
10*$12 + (N-10)*16 = $168
(N-10) *16 = $ 48
N-10 = 3
N=13
Hence, Sufficient
Option C
