If 80% of A = 20% of B and B = 5x% of A, then the value of x is:
The correct choice is: “80” From 80% of A = 20% of B: 0.8A = 0.2B, so B = 4A. B = 4A means B is 400% of A. Therefore 5x = 400, so x = 80. Check: 5 × 80 = 400%, and 400% of A…

If 80% of A = 20% of B and B = 5x% of A, then the value of x is:
Answer and explanation
Correct answer B
The correct choice is: “80”
From 80% of A = 20% of B: 0.8A = 0.2B, so B = 4A.
B = 4A means B is 400% of A. Therefore 5x = 400, so x = 80.
Check: 5 × 80 = 400%, and 400% of A = 4A = B.
