x is 40% of y and 50% of y is 40
50% of y = 40
\(\frac{y}{2}\)=40
y=80
x is 40% of y
x=\(\frac{40}{100}\)y
x=32
16 is 50% of x
Answer D
50% of y = 40
\(\frac{y}{2}\)=40
y=80
x is 40% of y
x=\(\frac{40}{100}\)y
x=32

0.4 * y = x
0.5 * y = 40
y = 80
So, x = 0.4 * 80 = 32
(16 / 32) * 100 = 50 %
Answer is D
0.5 * y = 40
y = 80
So, x = 0.4 * 80 = 32
(16 / 32) * 100 = 50 %
Answer is D
