Statement 1:
(1) The three cameras have an average price of $172.
(a+b+c)/3 = 172
(a+b+c) = $516.
Hence, insufficient Statement 2:
(2) Two are the same price and sell for $332 together
lets take price of b = price of c.
b+c = 2b = 332
b = 166 = c
Since, we don’t know the price of a.
Hence, insufficient
Combining Statements 1 and 2, we get
a+ b+ c = $516
a+ 332 = $516
a = $184
Hence, Sufficient
Option C
