We can dashed straight to option D,
Because we are given qrs>12
but we donot know the individual quantity
Case 1:
q = r = 1 and s= 12
Case 2:
q = 12, r= 1 and s = 1
Since all are positive numbers we can have numerous possibility
Hence option D

Multiply Quantity A and Quantity B by s - cancel out s on Quant. B
Quant A:
qrs/5
Quant B:
3
Multiply Quant A and Quant B by 5
Quant A:
qrs
Quant B:
15
Given qrs>12 and Quant B = 15:
If QRS = 13, then Quant A < Quant B
If QRS = 15, then Quant A = Quant B
If QRS = 16, then Quant A > Quant B
D is the correct choice.
Quant A:
qrs/5
Quant B:

Multiply Quant A and Quant B by 5
Quant A:

If QRS = 15, then Quant A = Quant B
If QRS = 16, then Quant A > Quant B
D is the correct choice.
