Mehta17 · Answer

Let price of first Camera be X, second be y and third be Z
Given, 
1) (X+Y+Z) / 3 = 172 
 > X+ Y + Z = 516

Not suff as price of ind cannot be determined

2) 2X = 332
 X= 166
Not suff as price of third camera cannot be determined

Using both 
From 1 - X+Y+Z = 516
From 2 - X - 166, again from 2 we know 2 camera has same price

Therefore, 2X+Y = 516 
Putting X = 166

We can find Y

Hence C

Dereno · Answer

We need to find the individual prices of three cameras. let the three cameras be a,b,c.

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

What are the individual prices of three cameras? (1) The three camera
