Answer:

42.9%

Step-by-step explanation:

Let say Cost Price of Pair of product A   =  A

Selling Price of Pair of Product A = A + (30/100)A = 1.3A

Profit = 0.3A

Let say Cost Price of Pair of product B   =  B

Selling Price of Pair of Product B = B + (50/100)B = 1.5B

Profit = 0.5B

Let say X Product sold of A  

10% more product of B Mean = 1.1X

Cost Price = AX +B(1.1X) =  AX  + 1.1BX

Profit = 0.3AX + 0.5B(1.1X) = 0.3AX + 0.55BX

Profit % = ((0.3AX + 0.55BX)/(AX  + 1.1BX) ) * 100

=> 45 = ((0.3AX + 0.55BX)/(AX  + 1.1BX) ) * 100

=> 45AX + 49.5BX = 30AX + 55BX

=> 15AX = 5.5BX

=> 15A = 5.5B

=> 30A = 11B

Let say Y products of B sold

Then 50% more product of A = 1.5Y

Cost Price = 1.5AY + BY

Profit = 1.5Y*0.3A + 0.5BY = 0.45AY + 0.5BY

Profit % =  (0.45AY + 0.5BY)/(1.5AY + BY) * 100

=> Profit % = (45A + 50B)/(1.5A + B)

= (90A + 100B)/(3A + 2B)   ( multiplying numerator & denominator by 2)

= (33B + 100B)/(1.1B + 2B)  ( using 30A = 11B  )

= 133B/3.1B

= 42.9%
