let x, y are the number of dozens of apples and bananas
=> x + y = 50  .............. (1)
and a, b are  the price of apples and banana for dozen
=> ax + by = 1050  ................... (2)
since the cost of apple = no of dozens of bananas & vice versa, we have x = b and y = a
So, the equation (2) becomes 2xy = 1050
xy =  525 …........(3)
by solving 1 & 3, we get
x & y = 35, 15
