Call the price of a dozen of eggs as x, the price of a bread of large size as y.
Since the price of 16 dozens of eggs and 10 breads of large size is 332, we have : 16x + 10y = 332.
Since the price of 10 dozens of eggs and 8 breads of large size is 225, we have : 10x + 8y = 225
10x + 8y = 225 -> 8/5(10x + 8y) = 8/5 x 225 - > 16x + 64/5y = 360.
-> 16x + 64y/5 - (16x + 10y) = 28.
-> 14y/5 = 28
-> y = 10.
Substitute y = 10 into 10x + 8y = 225, we get x = 14.5
So, the price of each dozen of eggs is 14.5 (whatever units) and the price of each bread of large size is 10 (whatever units)
