 Quantity A Quantity B x y

B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.

Kudos for R.A.E

As per the given statement

$$(10x + y) + (10y + x) = 1.43$$

or $$11x + 11y = 1.43$$

or $$x + y = \frac{1.43}{11} = 0.13$$

Since there is no possible ways to determine the value of x and y

So option is D
