Explanation

The question above tells us that 30% of A is 45% of B, and that the sum of A and B is 50.

We can translate both of these into equations:

0.30(A) = 0.45(B)

A + B = 50￼

We can solve for B in terms of A:

￼A = 0.45(B)/0.30 = 1.5(B)

Since A = 1.5B, we can plug 1.5B in for A in the second equation:

￼A + B = 1.5(B) + B = 50

2.5(B) = 50

B = 50/2.5

So, B = 20 and the**correct answer is (A)**.

We can translate both of these into equations:

0.30(A) = 0.45(B)

A + B = 50￼

We can solve for B in terms of A:

￼A = 0.45(B)/0.30 = 1.5(B)

Since A = 1.5B, we can plug 1.5B in for A in the second equation:

￼A + B = 1.5(B) + B = 50

2.5(B) = 50

B = 50/2.5

So, B = 20 and the
